The periodic table is organized into groups (vertical columns), periods (horizontal rows), and families (groups of elements that are similar). Elements in the same group have the same number of valence electrons. Meanwhile, elements in the same period have the same number of occupied electron shells.

Do all the elements in a group have similar physical properties?
Each element within a group has similar physical or chemical properties because of its atom’s outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
Are elements in the same group similar?
The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Do groups or periods share similar properties?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
What is difference between group and period?
Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.
Why do elements in the same group have similar properties in the periodic table?
The elements in the same group have similar chemical properties because they have the same valence shell electron configuration. The elements in a row show a gradual change in chemical properties because their valence shell electron configuration changes gradually along the row.
Do periods have similar chemical properties?
Elements within the same period have different number of electrons in their valence shells (the number is increasing from left to right) and different valence shell electron configuration. Therefore, elements in the same period are chemically different.
Which elements have similar physical properties?
The answer is b. Elements in the same group have the same number of valence electrons and so interact with other elements in a similar way. They display similar physical and chemical properties. For example, the halogens (F, Cl, Br, I) all react similarly.
How do you know if elements are similar?
Two different elements are likely to have similar chemical properties when they have the same number of valence electrons. Elements with the same number of valence electrons are found in the same column of the Periodic Table. Elements with the same valence shell are found in the same row on the Periodic Table.
What makes elements similar to each other?
Elements with the same number of valence electrons have similar chemical properties.
What do periods tell you on the periodic table?
The period number on the Periodic table tells you the total number of orbits that the atom will have. In other words, the period number indicates the number of energy levels (or energy orbit) of an atom. For example, 1st period indicates that these elements possess 1 energy shell (or energy orbit).
How do you remember periods and groups?
Mnemonic for Period 6: L(u)a HafTa Warna Reh Us(Os) Irritating Popat ke saath Aur Hoj(g)a pagal. Read as: La Hafta Warna Reh Us Irritating Popat ke saath Aur Hoja pagal. Period 7 contains the radioactive elements only. It includes actinides which include the heaviest naturally occurring element Californium.
Why is the periodic table arranged in groups and periods?
The discovery of the periodic recurrence of similar properties among the elements led to the formulation of the periodic table, in which the elements are arranged in order of increasing atomic number in rows known as periods and columns known as groups.
Do elements in the same group family or period have similar chemical properties?
Explanation: The elements of a group have similar chemical properties but in a period they have different chemical properties. This is because the chemicals properties depend on no of valence electrons.
Why do not elements present in a period show similar characteristics?
This is because the chemicals properties depend on no of valence electrons. As in a group all elements have same no of valence electron that’s why they have similar chemical properties but in a period the no of valence electron varies that’s why they differ in chemical properties.
Do periods have similar physical properties?
All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, elements in the same group (column) have similar chemical and physical properties, reflecting the periodic law.
Why do all elements in the same group have similar properties and in same period have different?
(a) (i) All the elements of a group have similar chemical properties because they have the same number of valence electrons in their outermost shell. (ii) All the elements of a period have different chemical properties because they have different numbers of valence electrons in their atoms.
What determines physical properties of an element?
All elements have differing physical properties depending on their bonding and their electronic structure. These properties very often determine their relationship with temperatures, textures and other substances when they are dissolved.
Do elements in the same column of the periodic table exhibit the same physical properties?
Explanation. The statement is correct. Elements in the same column have similar chemical and physical properties.
Do elements in the same group have similar chemical and physical properties?
So, we can say that elements in a group have the same physical and chemical properties because their atoms have the same number of valence electrons or same valence shell electronic configuration.
What 3 things elements in the same group have in common?
Answer and Explanation: Elements in the same group have the same number of valence electrons, and therefore have similar levels of reactivity. Every element is made of only one type of atom, and that atom has a unique number of protons, with varying numbers of neutrons and electrons.
What is the fastest way to memorize the periodic table?
- Break down the table into sections.
- Spread out the memorization process.
- Learn the elements in a song.
- Make nonsense words made from element symbols.
- Use color to learn element groups.
- Use a mnemonic device to help remember the order of the elements.
What is the rhyme to remember the periodic table?
Healthy Little Beggar Boys Catching Newts Or Fish. Hell, Here Little Beatniks Brandish Countless Number Of Flick kNives. Nagging Maggie Always Sighs, “Please Stop Clowning Around.” Here He Lies Beneath Bed Clothes, Nothing On, Feeling Nervous.
How can I memorize faster?
- Try to understand the information first. Information that is organized and makes sense to you is easier to memorize.
- Link it.
- Sleep on it.
- Self-test.
- Use distributed practice.
- Write it out.
- Create meaningful groups.
- Use mnemonics.
Can the periodic table be arranged differently?
But there are doubts over whether the periodic table is in the best possible configuration. Just as notes can be arranged in various ways to produce music, so the essence of the relationships between the elements could be depicted differently. There is no easy way to judge which is better, or more “true”.
