If you go backwards two elements, you will find Neon (Ne). If you go forwards six, you will find Argon (Ar). so the closest will be neon
The reaction of sodium bromide with chlorine gas is Cl₂(aq) + 2Na + 2Br? 2Na + 2Cl⁻ + Br²(aq).
<h3>What is sodium bromide?</h3>
Sodium bromide is an inorganic compound, white, crystalline with high melting point.
The reaction between halogens is redox reaction
Oxidation – 2Br⁻ ? Br₂ + 2e⁻ loss of electron.
Reduction – Cl₂ + 2e⁻ ? 2Cl⁻ gains of electron.
Thus, the correct option is Cl₂(aq) + 2Na + 2Br? 2Na + 2Cl⁻ + Br²(aq).

Answer: C. The non metal
Explanation:-
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The nomenclature of ionic compounds is given by:
1. Positive ion or metal is written first.
2. The negative ion or non metal is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
For example: 
, cesium is metal having an oxidation state of +1 called as 
cation and bromine 
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral called as cesium bromide.
The Kinetic Molecular Theory is a scientific model that states atoms in a compound are found in a constant state of motion (movement).
<h3>What is the Kinetic Molecular Theory?</h3>
The Kinetic Molecular Theory is a scientific model that states atoms in a compound are found in a constant state of motion (movement).
Thermal energy refers to the movement of particles and therefore both concepts are interrelated.
In conclusion, the Kinetic Molecular Theory is a scientific model that states atoms in a compound are found in a constant state of motion (movement).

Q1
<span>C. <span>Thermosphere</span> is the
layer of very rare air above the mesosphere. The air in this layer is so thin
that it would feel freezing cold to us. Many satellites actually orbit Earth
within the thermosphere so it is more like outer space than a part of the
atmosphere. Variations in the amount of energy coming from the Sun exert a
powerful influence on both the height of the top of this layer and the
temperature within it. </span>
Q2
<span>A. <span>Nitrogen and oxygen are the two most common gases that composes the atmosphere; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower
amounts; each makes up less than 1% of the atmosphere's mixture of gases.
The atmosphere also includes
water vapor.</span></span>

Barometric pressure is
the pressure that the atmosphere exerts on an object</span>
