Protons and Neutrons: What Are They?Jean Louis Van Belle
An atom has 20 electrons and 20 neutrons. What is the mass of this atom? What charge would an ion that has 11 protons, 11 neutrons, and 10 electrons would have? What is the difference between protons, neutrons, and electrons? How many protons, electrons, and neutrons are in Hydrogen-3...
The collapse of massive stellar cores results in an object that has from one to two times the mass of the sun, but only has a width of between 6 and 12 miles (10 and 20 kilometers). Imagine the sun reduced in size until it is a sphere that sits comfortably within the city of New...
Atoms have several characteristic parts, namely a nucleus of protons and neutrons, surrounded by electrons. Protons have a positive charge, neutrons are neutral, and electrons have a negative charge. Answer and Explanation:1 The electrons of an atom are arranged in energy levels. These levels are...
But the dense core continues to collapse, generating pressures so high that protons and electrons are squeezed together into neutrons, as well as lightweight particles called neutrinos that escape into the distant universe. The end result is a star whose mass is 90% neutrons, which can't be ...
Dark matter doesn't interact with light as does matter composed of atoms made of protons and neutrons, part of the baryon family of particles, that surrounds us every day and is known as "baryonic matter." Dark matter is, therefore literally "'dark" and thus the prefix in "dark matter...
If you look inside an atom, you find tiny particles called protons, neutrons, and electrons. Atoms of each element have different numbers of these particles. Protons and electrons have electrical charges. You can think of this as being similar to a battery, which has a + (positive) and -...

Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic nuclei). Neutron The neutron is a subatomic particle, symbol n or n0, which has a neutral (not positive or negative) charge, and a mass slightly...
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
