Question

Give scientific reason:-

• Atom is electrically neutral.
• Atomic mass number is a whole number.
• Atoms are stable though negatively charged electron are revolving within it.

Answer 1

Answer:

1. A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.

2. Atomic number and mass number are always whole numbers because they are obtained by counting whole objects (protons, neutrons, and electrons). The sum of the mass number and the atomic number for an atom (A-Z) corresponds to the total number of subatomic particles present in the atom.

3. Atoms are stables though negatively charged electrons are revolving within it because each atom contains equal numbers of protons and electrons. So, the charge on negatively charged electrons is balanced by a charge on the positively charged proton. Therefore, the atom is electrically neutral and stable.

Answer 2

Answer:

because protons= electrons

atom is stable so it's neutral

it will only exist if it's neutral

many experiment prove it

protons= electrons so it's stable
