Barium belongs to Group 2, so there are 2 valence electrons
2 is the standard number of valence electrons
It will lose 2 electrons.
No. An ion is a positively or negatively charged atom, or group of atoms due to more or less electrons than necassary. Both barium and sulfate are ions, but together they are a compound, not an ion. Barium Sulfate is a chemical compound made up of two ions, a barium ion and a sulfate ion. A Barium ion is Ba+2, meaning it has two less electrons that a barium atom has. The reason for this is because the barium atom has 56 total electrons. Every atom wants to be ion with a filled valence shell, that is to have the same or similar electronic configuration of a noble gas (the elements in the right most column). The valence shell is the outermost shell of electrons and for barium the other shell is 8 electrons. In order for Barium to do this, it has to somehow lose 2 electrons to become similar to Xenon's electronic configuration. Sulfate, SO4 -2, is also an ion. the -2 means it has aqcuired 2 more electrons from another ion. It got those two electrons from the barium atom, simultaneously making the barium atom a barium ion. Sulfate is called a polyatomic ion, meaning an ion made up of more than 1 atom. When the barium ion gives the sulfate ion two electrons, thus making both electronic configurations "happy" they bond together to make an ionic bond, creating the compound barium sulfate.
In the ion of barium, two electron are lost to follow the octet rule (to have a complete valence electron shell).
Barium has two valence electrons, as can be deduced from its placement in Group 2 of the modern periodic table.
There are 2 valence electrons in Barium.
A barium atom has two 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.
Barium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, barium has 2 valence electrons.
the number valence shell of an barium is can be found in the other network
It will lose 2 electrons.
Two electrons are donated by Barium to an oxidant (nonmetal, eg. O2) by which barium gets oxidised.Ba --> Ba2+ + 2e-This is because Ba is in group 2 of the periodic system, belonging to the 'earth alkali' metals and so it has 2 electrons (2e-) in its valency (or outer) shell (2,8,18,18,8,2). Hence Ba2+ configuration is (2,8,18,18,8,-), with an empty (-) 6th shell (the 'P' shell) like Xenon.
