Do periods or families have 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.

Do periods contain elements with similar properties?

False, elements in the same period (row) have different properties. Elements in the same group (column) have similar properties. The periodic table is a way to organize the elements in a single representation. The table is divided into groups and periods where groups are the columns and periods are the rows.

Why do elements in the same period have similar physical properties?

The physical and chemical properties of elements depend on the number of valence electrons. Elements present in the same group have the same number of valence electrons. Therefore, elements present in the same group have similar physical and chemical properties.

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 common between elements in the same period?

All the elements in same period have same number of shells e.g., all elements in period 3 have 3 shells each i.e., each have same valence shell.

What elements have similar properties?

Elements in the same column of the Periodic Table have similar chemical properties. So what does that mean about their valence electrons? You guessed it! Elements in the same column of the Periodic Table have the same number of valence electrons – that’s why they have similar 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.

What is similar about the elements in the 7 periods?

There are seven periods total and each element in a period has the same number of atomic orbitals. The top period, which contains hydrogen and helium, has only two orbitals. As you go down the rows, the number of orbitals increases.

Why do elements of a period have different properties?

(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.

Why do elements in periodic table have similar chemical properties?

Reason: Elements in a group have the same number of electrons in the outermost shell hence they have similar chemical properties.

What do periods have in common?

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.

Do elements in the same column of the periodic table exhibit the same physical properties?

The elements can be classified as metals, nonmetals, or metalloids. The elements within the same group of the periodic table tend to exhibit similar physical and chemical properties.

How are periods and groups different from each other?

Groups and periods are two ways of categorizing elements in the periodic table. 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.

What are 3 elements that have similar properties?

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.

Where do you find similar elements in periodic table?

Elements that have similar chemical properties are grouped in columns called groups (or families).

How do you know if elements are similar?

What are the properties of the group or period?

Periods: The elements have electrons in the same outer shell, i.e. the rows. 2. Groups: The elements have the same number of electrons in their outer shells, i.e. the columns.

What does the period number tell you about an element?

The period number is related to the number of electron occupied shells in the element and the period number is linked to its valence electrons.

What is unique about the seventh period?

All elements of period 7 are radioactive. This period contains the actinides, which includes plutonium, the naturally occurring element with the heaviest nucleus; subsequent elements must be created artificially.

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.

What are the properties of the elements in the periodic table?

  • Chemical Group Block.
  • Standard State.
  • Atomic Mass, u.
  • Electron Configuration.
  • Oxidation States.
  • Electronegativity (Pauling Scale)
  • Atomic Radius (van der Waals), pm.
  • Ionization Energy, eV.

Why do all the members of a group have similar properties?

Elements in the same group have similar properties because they have the same number of valence electrons in their outermost shell. Elements in the same period have different properties because the number of valence electrons in their outermost shells differ.

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.
