(a)
To determine: The element that consists of 30 protons.
Introduction: An atom is known as the building block of all the matter present in the universe. It is made up of three subatomic particles: protons, neutrons, and electrons. The protons are positively charged sub-atomic particles that are present with the neutrons in the nucleus.
(b)
To determine: The number of electrons present in one atom of calcium.
Introduction: Electrons are the negatively charged sub-atomic particles found revolving in orbits around the nucleus in the atom. It is an elementary particle because it cannot be broken into smaller particles.
(c)
To determine: The atomic number, average atomic mass, and letter symbol for iodine.
Introduction: The atom is made up of three subatomic particles: protons, electrons, and neutrons. The atomic number of the element is the same as that of the protons present. The atomic mass is equal to the sum of the protons and neutrons present in the atom.
