Elements in a vertical group (Group 1, Group 2, etc.) of the periodic share in common the same number of valence electrons. The valence electrons are the electrons in the outer shell of an atom, and their number has a lot to do with their chemistry.
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
First off, there is no "salt" on the periodic table of the elements. Salt is a compound. However, you may be talking about "sodium". If that's the case, sodium is NOT in the same column as oxygen in the periodic table. Sodium is in the first column while oxygen is in the sixteenth column.
a family is a column of elements a period is a row of elements
Some common questions about the periodic table include: What is the periodic table? How is it organized? What do the numbers and letters on the table represent? Why are some elements grouped together? How many elements are there in total?
Yes, elements in the same column of the periodic table (also known as a group) have the same number of valence electrons. This common valence electron configuration gives them similar chemical properties.
They have the same Valency
Elements in a given column have the same number of valence electrons and hence the similar properties.
Chemicals in a column, or "group" have similar chemical properties.
they all have the same electrons.

The noble gases, column 18 in the most common modern periodic table.
Elements in same column have equal number of valence electrons. so they possess similar chemical properties.
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
A group of elements.
