. 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.

The formula for barium ion is Ba^2+ and the formula for hydroxide ion is OH^-. When they combine to form barium hydroxide, the formula is Ba(OH)2.
The formula for barium ion is Ba^2+, indicating a barium cation with a +2 charge. The formula for hydroxide ion is OH-, representing a hydroxide anion with a -1 charge.
Barium hydroxide (Ba(OH)2) is formed when a barium ion (Ba2+) reacts with a hydroxide ion (OH-) in a chemical reaction.
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 Lewis dot structure for the oxide ion (O2-) consists of the oxygen atom with 8 valence electrons, 6 from the lone pairs and 1 from each of the two negative charges. The oxygen atom will have a full octet, represented by 8 dots around the symbol.
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 of the barium ion is simply "barium ion." It is a cation with a charge of +2, formed when barium (Ba) loses two valence electrons.
The Lewis structure of BaCl2 shows barium (Ba) in the center with each chlorine (Cl) atom bonded to it, resulting in a linear shape. Barium has a charge of +2, while each chlorine atom carries a charge of -1. The Lewis structure showcases two lines connecting Ba to each Cl, representing the ionic bond.
