Question

Explain:

1. Nucleus of an atom carries positive charge

II. Most of the space in an atom is empty.

III. The whole mass of the atom is located in the centre of the atom​

Answer 1

Answer:

1. Nucleus of an atom carries positive charge

= The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

II. Most of the space in an atom is empty.

= most of the space in atom is empty because atoms contain electrons whose mass is negligible.so the nucleus contain all the mass of the atom as having both neutrons and protons. ... therefore because of this most of the space in atom is empty.

III. The whole mass of the atom is located in the centre of the atom

= An atom consists of a small positively charged nucleus at its center. 2. The whole mass of the atom is concentrated at the nucleus. 3.
