Answer:
As for my own understanding. I think the answer I B= because it has three valence electron
In 1905 Albert Einstein had proposed a solution to the problem of observations made on the behaviour of light having characteristics of both wave and particle theory. From work of Plank on emission of light from hot bodies, Einstein suggested that light is composed of tiny particles called <span>photons, </span>and each photon has energy.
Light theory branches in to the physics of <span>quantum mechanics, </span>which was conceptualised in the twentieth century. Quantum mechanics deals with behaviour of nature on the atomic scale or smaller.
As a result of quantum mechanics, this gave the proof of the dual nature of light and therefore not a contradiction.
The electrostatic potential is the work done to remove the charge. The molecule showing the potential map shows that it is HI.
<h3>What is electronegativity?</h3>
Electronegativity is the elemental property to attract the electron toward the atom and is affected by atomic number and the atomic radius. The map shows that the molecule is made of two different atoms and has linear geometry.
Due to the linear geometry, the molecule cannot be Br₂ and SO₃ as they are nonpolar and nonlinear respectively. Similarly, BrF and ICl can be eliminated as they are interhalogen compounds. In the HI molecule, the hydrogen atom is a cation and the iodine atom is an anion that has high electronegativity differences.
Therefore, HI is the molecule depicted in the potential map.

<span>Atomic mass is, literally, a measure of mass.
</span><span>One atomic mass unit is a very, very, very, very, very, very small fraction of a gram.
It is actually defined using the most common isotope of carbon, which is carbon-12.
The average atomic mass of Oxygen is 15.999 u. </span>
