States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

## Explanation:
In each blank box, place the appropriate subscript and superscript values that indicate the isotope symbol. For example:
- The first (vertical) box indicates the __mass number__ (total number of protons and neutrons).
- The second (horizontal) box indicates the __atomic number__ (number of protons).
- The third (box on the right) denotes the __element symbol__.
These values can be determined based on the descriptions provided and matched against the options given in the problem.
For educational purposes, it is essential to understand:
- The **atomic number** is equal to the number of protons in an element and can also be derived from the number of electrons for neutral atoms.
- The **mass number** is the sum of protons and neutrons in the nucleus.
- The number of **neutrons** can be derived from the difference between the mass number and the atomic number.
The isotope symbol is commonly written in the form:
$$
\frac{Mass \: Number}{Atomic \: Number} \: Element \: Symbol
