. Sr .
There should be two valence electrons around the element since Strontium is in the second column of the Periodic Table and has two valence electrons filling the 5s shell.
When a barium atom forms an ion, it loses two electrons to achieve a stable octet configuration like a noble gas. This results in the formation of a Ba2+ ion with a 0 oxidation state.

Barium ion = Ba2+ Hydroxide ion = OH-
Barium ion = Ba2+ Hydroxide ion = OH- The compound they make is Barium hydroxide = Ba(OH)2which is a precipitate insoluble in water.
When barium ion is added to a hydroxide ion, the two opposite charges attract each other to form barium hydroxide Ba2+ + OH------>Ba(OH)2.
When a barium atom forms an ion, it loses two electrons to achieve a stable octet configuration like a noble gas. This results in the formation of a Ba2+ ion with a 0 oxidation state.
In the Lewis dot structure for the phosphate ion (PO₄²⁻), you would represent 32 electrons - 5 from phosphorus and 7 from each of the four oxygen atoms, for a total of 32 electrons.
The Lewis dot structure of the bicarbonate ion (HCO3-) consists of one hydrogen atom, one carbon atom, and three oxygen atoms. The carbon atom is double-bonded to one of the oxygen atoms and has a single bond with the other two oxygen atoms. Each oxygen atom has two lone pairs of electrons around it.
The Lewis dot structure of the nitronium ion (NO2+) consists of a nitrogen atom double bonded to one oxygen atom, which is also single bonded to another oxygen atom. The nitrogen atom carries a positive charge and has no lone pairs.
The dot structure for IO4 starts with the I atom in the center. from this, there are three doubly bonded O atoms and one singly bonded O atom. The O atom has three pair of dots and the others have two pair of dots. The structure is then bracketed and noted with a 1- superscript.
The Lewis dot structure for the formate ion (HCOO-) consists of one carbon atom in the center bonded to two oxygen atoms and one hydrogen atom. The carbon atom has a double bond with one oxygen atom and a single bond with the other oxygen atom. The hydrogen atom is bonded to one of the oxygen atoms.
In the Lewis dot structure of CaCl2, calcium (Ca) will have two dots (representing its two valence electrons) next to it and each chlorine (Cl) atom will have seven dots around it (representing its seven valence electrons). In the cross structure, Ca is represented at the center with Cl atoms around it pointing towards it, indicating the sharing of electrons.
The name for this ion is:barium ion
Barium nitride is a "salt like" nitride- which means that he bonding is best considered as ionic. the lewis dot is your method of showing ions Ba2+ ion and an N3- ion, this is sometimes done with the outer shell shown complete, which is 8 electrons for both ions.

A barium ion is denoted as Ba^2+.
