(ii) proton (iii) neutron​

Answer 1

mass

1. 1/2000 × mass of proton
2. 1 u
3. neutron -1 u

Explanation:

charge

1. electron = -1
2. neutron = 0
3. proton = +1

Answer 2

1) Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).

2)Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel each other and unlike charges attract each other.

3)An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. ... The charge on a single electron is considered as the unit electrical charge.

4 and 5 .)Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge. ... Neutrons have no charge.
