What is the element
The element which is a non-metal and present in the same group as lead is carbon as they both have four electrons in their valence shell.
An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

(2) The rate of the forward reaction must equal the rate of the reverse reaction.
(3) The concentration of the reactants must equal the concentration of the products.
(4) The potential energy of the reactants must equal the potential energy of the products.
Answer: The correct answer is Option 2.
Explanation:
Reversible reaction is defined as the reaction in which the products formed react together to give the reactants back. For general reversible chemical equation:
At equilibrium, the rate of forward reaction is equal to the rate of backward reaction.
Rate of forward reaction:
Rate of backward reaction:
At equilibrium, =
Thus, the correct answer is Option 2.
