When a barium atom loses two electrons what charge does it have

Chemistry
1 answer:
Darya [45]3 years ago
6 0

Answer:

It becomes a positive ion and its radius decreases

Explanation:

As per the Octet rule, Barium has 2 electrons in its outermost shell. When it loses the two electron it gains two positive charge i.e Ba2+. As the barium loses the two electron from its outermost shell, the outermost shell becomes vacant and thus is no more considered as a part of atomic geometry of the barium atom and since the outermost shell is considered negligible the radius of barium atom reduces automatically.

Explain the purpose and function of a gene.
Kryger [21]

Function

Genes decide almost everything about a living being. One or more genes can affect a specific trait. Genes may interact with an individual’s environment too and change what the gene makes.

Genes affect hundreds of internal and external factors, such as whether a person will get a particular color of eyes or what diseases they may develop.

Some diseases, such as sickle-cell anemia and Huntington’s disease, are inherited, and these are also affected by genes.

Purpose

The purpose of genes is to store information.

Each gene contains the information required to build specific proteins needed in an organism.

Hope this helps !!

What is the formula mass for carbon dioxide?
scZoUnD [109]
The molecular mass of the compound CO2 is calculate by simply taking the number of atoms of each element and multiplying it by the molar mass of the element on the periodic table.

C = 1 • 12.0 g/mol
O2 = 2 • 16.0 g/mol = 32.0 g/mol
CO2 = 12.0 + 32.0 = 44.0 g/mol.

The formula mass of CO2 is 44.0 g/mol.
