Solution : Elements in the same period have the same outermost shell for different outermost electronic configuration and hence have different physical and chemical properties. However, elements in the same group have similar outermost electronic configuration have similar physical and chemical properties.

Are similar elements the same period?
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.
Do elements in same group have similar properties?
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.
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.
Does period have similar properties?
Elements in a group generally possess similar properties, but elements along a period have different properties.
How do you know if elements have similar properties?
Some characteristics of the elements are related to their position on the periodic table. The number of valence electrons of an element can be determined by the group (vertical column) number in the Periodic Table. Elements with the same number of valence electrons have similar chemical properties.
What remains same in a period?
Elements present in horizontal rows are called periods. Elements belonging to the same period have same no. of the shell as the electrons are added in the same shell of the element.
What is common among the elements in the same period?
Solution : (a) The elements belonging to the same period have same number of shells. For example, the elements placed in the second period have two shells (K, L). Similarly, the elements included in the third period have three shells (K, L, M).
What is true about elements in the same group?
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.
Why don t elements in the same periods share many of the same properties?
4) Why don’t elements in the same periods share many of the same properties? Elements in the same periods have electrons in the same energy level, but it turns out that the energies of the electrons is nowhere near as important as how much elements want to gain or lose electrons to achieve a full octet.
Why do elements in the same group show similar properties?
The elements of same group have similar chemical properties because they have same number of valence electrons.
Why elements in the same family have similar properties?
Because the members of each group in the main group elements has the same number of valence electrons, there are similar properties and similar trends in chemical reactions found in the group.
What determines physical properties of an element?
The properties of an element are determined largely by the electrons in its shell.
Are elements more similar in groups or periods?
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.
What three elements have similar properties to one another?
Answer and Explanation: Elements present in the same group of the periodic table have similar physical and chemical properties. Therefore of all the given triplets, only Sodium, Potassium and Rubidium have similar physical and chemical properties.
Which elements have the most similar properties?
Answer and Explanation: The elements that have the most similar chemical properties are those in the same group, or column of the periodic table. Elements are placed in order of atomic number and end up in vertical groups that have the same number of valence electrons and therefore similar chemical properties.
Why the number of elements is different in different periods?
Elements in a period share the highest unexcited electron energy level. There are more elements in some periods than others because the number of elements is determined by the number of electrons allowed in each energy sub-level.
Why are the elements in the same group or period?
Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods.
What two elements have common properties?
The elements potassium and sodium have similar chemical properties because they have the same number of valence electrons (1).
Do chemical elements have physical properties?
These properties include color, density, melting point, boiling point, and thermal and electrical conductivity. While some of these properties are due chiefly to the electronic structure of the element, others are more closely related to properties of the nucleus, e.g., mass number.
Why do metals have similar properties?
A metal. Elements within the same group/family of the periodic table have what? Similar properties because they have the same number of valence electrons. Electrons in the outer level of an atom available to be lost, gained, or shared.
Do elements in the same period have the same number of neutrons?
Elements in the same period have: the same number of neutrons. gradually changing properties. similar symbols.
Do elements in the same period have same number of valence electrons?
Answer: Yes. All these elements contain the same number of shells, i.e., two shells – Kand L.
Inference: From this activity, we learn that the in a period, all elements have same number of shells but not same number of valence electrons.
What do elements in the same period have in common quizlet?
What do elements in the same period have in common? They have the same number of occupied energy levels. What do elements in the same group have in common? They have similar chemical properties and the same number of valence electrons.
Why don t the elements within an A group in the periodic table have identical properties?
Why don’t the elements within an A group in the periodic table have identical properties? Elements in the same A group do not have identical properties because their valence electrons are in different energy levels.
