Simple to make them easier to recognize.
Not families, Periods (Apex)
Sodium and calcium belong to the alkali metal and alkaline earth metal families, respectively. Sodium is in group 1 of the periodic table with elements like lithium and potassium, while calcium is in group 2 with elements like magnesium and strontium.
A family is a vertical column in the periodic table. Elements in a family all share similar characteristics, whether they be physical or chemical. There are 18 family (or group) columns in the periodic table.
$oo
The elements are arranged in increasing ATOMIC NUMBER. NOTE ; NOT atomic mass. The atomic Number = Number of protons = the number of electrons in the neutral atom. NB A different number of protons is a different element.
The vertical columns are groups or families. There are 18 such families.
elements are grouped together into families as they have simliar properties. all the elements in each collum or period have imilar chamical properties.

The elements in vertical group are called families because the elements possess same characteristics.
The elements in vertical group are called families because the elements possess same characteristics.
A nuclear family consists of a mother, father, and kids.
There are 18 families. They are made according to the properties of elements. So the elements in a group has similar properties.
I have lots of families
Families of elements with similar chemical properties are called "groups" or "families" on the periodic table. Elements within the same group typically have the same number of valence electrons, which gives them similar reactivity and chemical properties.
Families. Periods are similar Elements of increasing weight, within the same families
There are 18 families. They are made according to the properties of elements. So the elements in a group has similar properties.
The elements in the same families (columns) are the most similar.
