The elements in the same column of the periodic table share the number of electrons in the outer shell (vallence electrons.) The most electrons that can be found in the outer shell is 8. After the column number extends further than 8 you subtract 10 from the number. That meaning hydrogen, the first element on the periodic table, would have one electron on its outer shell.

RossElements in the same group of the Periodic Table share similar chemical properties. They have the same number of valence electrons and tend to form similar types of compounds. As you move down a group, the elements increase in atomic size and reactivity.

What is a group of elements in the periodic table?
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.
Which elements occupy the same group in the periodic table?
Elements that have similar chemical properties occupy the same group on the Periodic Table.
Which two elements are in the same group or family?
According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.
What is the difference3 between a family of elements and elements in the same period?
a family is a column of elements a period is a row of elements
What are the groups on the periodic table and how do they relate to the periodic period of elements?
The groups on the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. The periodic period of elements refers to the horizontal rows on the periodic table, which indicate the number of electron shells an element has. Elements in the same period have the same number of electron shells, but elements in the same group can be in different periods.
