An electron is not an element.
An elements period is determined by the number of electrons it has in its outer shell.
Elements in the same family (or group) have the same amount of electrons in their outer shell. For Example, all elements in Group 1 have 1 electron in their outer shells.
alkali metals (group 1 elements)
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
The elements in this group are called Alkali Metals.

because they have outer electrons than can merge with other elements. all elements want to have full outer electron shells, and they only have a few outer electrons.

All of them has one electron in their outer shell.
An outer electron shell with only one electron.
Elements in the same family (or group) have the same amount of electrons in their outer shell. For Example, all elements in Group 1 have 1 electron in their outer shells.
alkali metals (group 1 elements)
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
They all have one electron in the outer most shell
Elements in Sodium's Group (Group 1 - Alkali Metals) will have the same amount of electrons in their outer shell (i.e. 1 electron in the outer shell).
Electron configuration - they have the same number of elements in their outer 'electron shell'. This induces them to have similar bonding properties, and so elements in the same group are chemically similar.
