The correct answer is a photon.

A photon refers to a particle signifying a quantum of light or other electromagnetic radiation. A photon carries energy equivalent to the radiation frequency, however, exhibits zero rest mass.

A subatomic particle refers to a unit of energy or matter, that is, the basic makeup of all the matter. On the basis of modern atomic theory, an atom exhibits a nucleus, also known as the core or its center. The nucleus comprises subatomic particles, that is, neutrons and protons. The neutrons are neutral particles, and the protons are positively-charged particles. A cloud of very small subatomic particles known as electrons surrounds the nucleus. The electrons are negatively charged particles.

Determine the formula of chromic acid.

Katyanochek1 [597]

<u>Answer:</u> The formula of chromic acid is $H_2CrO_4$

<u>Explanation:</u>

We are given an ionic compound named as chromic acid. This acid is formed by the combination of hydrogen ion and chromate ion.

An acid is defined as the substance which releases hydrogen ion when dissolved in water.

Hydrogen is the 1st element of periodic table having electronic configuration of $1s^1$ .

This element will loose 1 electron to form $H^{+}$ ion.

Chromate ion is a polyatomic ion having chemical formula of $CrO_4^{2-}$

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for the given compound is $H_2CrO_4$

Thus, the formula of chromic acid is $H_2CrO_4$
