The statement that is true about the subatomic particle is

$\boxed{{\text{Electrons are the subatomic particles with the smallest mass}}}$

Further explanation:

Atom is the building unit of matter and is the smallest particle that an element can possess. The central part of an atom is called atomic nucleus. There are three subatomic particles, namely protons, electrons and neutrons in an atom. Out of these three, protons and neutrons reside in the nucleus of the atom while electrons revolve around the atomic nucleus in definite orbits.

Proton is the subatomic particle that carries a positive charge, electrons are negatively charged and neutrons are neutral with no charge on them.

Protons are the only subatomic particles to have charge.

Only neutrons have no charge whereas both protons and electrons are charged subatomic particles. Therefore this statement is false.

Electrons are the subatomic particles with the smallest mass.

The mass of an electron is $9.1 \times {10^{ - 31}}{\text{ kga}}$ , that of protons is $1.6726219 \times {10^{ - 27}}{\text{ kg}}$ and that of neutrons is $1.674927471 \times {10^{ - 27}}{\text{ kg}}$ . So the mass of electrons is the smallest among all the subatomic particles. Therefore this statement is true.

Neutrons orbit the nucleus of the atom.

Neutrons and protons are located inside the nucleus of an atom while electrons revolve around it in definite orbits. Therefore this statement is false.

Subatomic particles all have the same mass.

The mass of an electron is $9.1 \times {10^{ - 31}}{\text{ kg}}$ , that of protons is $1.6726219 \times {10^{ - 27}}{\text{ kg}}$ and that of neutrons is $1.674927471 \times {10^{ - 27}}{\text{ kg}}$ . The mass of protons and neutrons is almost same but that of electrons is quite different from masses of the other two particles. Therefore this statement is false.

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.
