Step-by-Step Text Solution:1. Identify the Subatomic Particles: An atom is composed of three main subatomic particles. 2. Name the First Particle: The first subatomic particle is the <st
Today, atomic research is focused on studying the structure and the function of matter at the subatomic level. This not only consists of identifying all the subatomic particles that are thought to make up an atom, but investigating the forces that govern them. These include strong nuclear forces...
The majority of an atoms' mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom's constituent particles, with a mass of 9.11 x 10-31kg and a size too small to be measured by current techniques. Protons have a mass that is 1,83...

There are three different subatomic particles in an atom. The nucleus of an atom is composed of protons and neutrons, which are tightly packed together. Orbiting the nucleus, we find the tiny, negatively charged particles known as electrons....
4.2 The Structure of an Atom Atom is the smallest particle of an element. Atoms cannot be divided into anything smaller. What is an atom made of? Three subatomic particles: – Proton – Neutron – electron + PROTONS + Positively charged subatomic particle Found in the nucleus of an atom –...

The nucleus was discovered in 1911 by Ernest Rutherford, a physicist from New Zealand, according to theAmerican Institute of Physics. In 1920, Rutherford proposed the name proton for the positively charged particles of the atom. He also theorized that there was a neutral particle within the nucle...
particles called electrons that move in orbits around the nucleus. Most of the mass of the atom is contained in the nucleus and the mass of the proton and neutron are about the same. However, the nucleus is a small portion of the total amount of space the atom takes up. Different types...
