Detailed explanation-1: -The nucleus contains the majority of an atom’s mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom’s volume. The diameter of an atom is on the order of 10−10 m, whereas the diameter of the nucleus is roughly 10−15 m-about 100, 000 times smaller.
Detailed explanation-2: -Electrons are the least massive of an atom’s constituent particles, with a mass of 9.11 x 10-31 kg and a size too small to be measured by current techniques.
Detailed explanation-3: -There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.
Detailed explanation-4: -Atoms are the smallest units of matter that have all the characteristics of an element. Atoms combine to form molecules. Atoms are composed of smaller particles known as protons, neutrons, and electrons.
