Answer:
represents the additional driving force required to overcome barriers such as the large activation energy for the formation of a gas at a metal surface.
Seven diatomic elements are H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂.
<h3>Which are diatomic molecules?</h3>
Diatomic molecules are those molecules in which two atoms of same elements are present, and they are combined to attain the stability.
The seven diatomic molecules which are exist in the chemistry are:
- Hydrogen gas (H₂)
- Chlorine gas (Cl₂)
- Nitrogen gas (N₂)
- Fluorine gas (F₂)
- Bromine gas (Br₂)
- Iodine gas (I₂)
- Oxygen gas (O₂)
Hence H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂ are 7 diatomic molecules.

The properties of malleability and ductility can all be explained on the basis of metallic bonding.
<h3>What is malleability?</h3>
The term malleability refers to the ability of a metal to be hammered into sheets. It is a very important property of metals that helps in metal work. The images are not shown here hence the question is incomplete.
Ductility refers to the ability of metals to be drawn into sheets. This is the reason why metals can be used to make wires. All these properties are explained on the basis of metallic bonding.

Answer:
A. 1 = 3 - 2
Explanation:
What defines an expression?
expression - An expression is a sentence with a minimum of two numbers and at least one math operation. This math operation can be addition, subtraction, multiplication, and division.
So if we look at the letter options we can see that A is the best choice.
