Question

The mass number of an neutral element is 396 and neutron number is 156. Find (a) Proton b) Electron​

Answer 1

Answer:

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.

Introduction

The Bohr model is outdated, but it depicts the three basic subatomic particles in a comprehensible way. Electron clouds are more accurate representations of where electrons are found. Darker areas represent where the electrons are more likely to be found, and lighter areas represent where they are less likely to be found.

Particle Electric Charge (C) Atomic Charge Mass (g) Atomic Mass (Au) Spin

Protons +1.6022 x 10-19 +1 1.6726 x 10-24 1.0073 1/2

Neutrons 0 0 1.6740 x 10-24 1.0078 1/2

Electrons -1.6022 x 10-19 -1 9.1094 x 10-28 0.00054858 1/2
