Barium belongs to Group 2, so there are 2 valence electrons
2 is the standard number of valence electrons
It will lose 2 electrons.
The name for this ion is:barium ion
In the ion of barium, two electron are lost to follow the octet rule (to have a complete valence electron shell).
Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
There are 2 valence electrons in Barium.
A barium atom has two valence electrons.
Barium has two valence electrons, as can be deduced from its placement in Group 2 of the modern periodic table.
2 is the standard number of valence electrons
Barium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, barium has 2 valence electrons.
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
6 orbital shells. Inner orbital shell (1st shell) containing 2 electrons. Next shell (2nd shell) containing 18, next containing
It will lose 2 electrons.

Barium (Ba) has 2 valence electrons in its outer shell. Therefore, it does not have any 5p electrons.
In the ion of barium, two electron are lost to follow the octet rule (to have a complete valence electron shell).
When barium and oxygen are brought together in a chemical reaction, they will likely form barium oxide (BaO). Barium will tend to lose its two valence electrons, while oxygen will tend to gain two electrons to form a stable compound.
