Question

Which statement is true regarding atoms.?

a) electrons and neutrons must be equal neutrons have no mass or charge protons and neutrons make up most of the atoms mass and are located in the nucleus.
b) electrons make up most of the mass and are located in the cloud or in orbitals protons and electrons have unequal charges and opposite signs

Answer 1

Protons and neutrons make up the majority of an atom's mass and are found in the nucleus, while electrons, which are much lighter, orbit in a cloud around the nucleus. Neutrons have no charge, and protons and electrons have equal but opposite charges.

Step-by-step explanation:

The correct statement regarding atoms is that protons and neutrons make up most of the atom's mass and are located in the nucleus while electrons are located in the cloud or in orbitals around the nucleus. Electrons and protons have electrical charges that are identical in magnitude but opposite in sign, with electrons having a charge of -1 and protons a charge of +1. Neutrons have no charge and approximately the same mass as protons. The mass of a proton or neutron is about 1836 times greater than the mass of an electron, and thus they constitute the bulk of the mass of atoms.
