Valence electrons describe the number of available electrons for bonding. The group number describes outermost electron. The elements in same group has same valence electrons.
The number of electrons available for bonding are the valence electrons. In an element, the group number is equal to the number of valence electrons. So the number of electrons available for bonding can be identified by the group number.
Bromine has 7 valence electrons available for bonding.
All of the elements, apart from the transition metals in the middle, are divided into groups. Group 1 elements have 1 electron in their outer shell, and this is the electron used in bonding. Group 2 have 2 electrons, Group 3 elements have 3, and so on. Group 8 elements have a full outer shell, so they generally don't react.
Valence electrons are the electrons available for bonding. Valence electrons are the electrons in the outermost energy level of an atom and they are involved in forming chemical bonds with other atoms.
The number of the vertical column- or group- that the particular element is in indicates the number of valence electrons available for bonding. For example, Lithium has one valence electron, whereas oxygen has six.
Calcium has the same number of electrons available for bonding as magnesium. Both elements have 2 electrons available for bonding in the outer shell.

These are the valence electrons.

You can find this information from the periodic table.
The number of the vertical column- or group- that the particular element is in indicates the number of valence electrons available for bonding. For example, Lithium has one valence electron, whereas oxygen has six.
Lithium have available for bonding one electron.
Calcium has the same number of electrons available for bonding as magnesium. Both elements have 2 electrons available for bonding in the outer shell.
Two valence electrons
number of electrons in the bonding shell vary according to the element. for example group 1 in the periodic table contains elements with ony one electron in their bonding shell, similarly group 2 has elements with two electrons in its bonding shell and so on. the group number in the periodic table denotes the number of electrons in the bonding shell of each element present in that particular group
Argon is a noble gas and being as its highest energy level is completely filled there are no electrons available for bonding in argon.
It would belong to group XVI, the group with oxygen.
