What is a group of atoms that acts together as one charged atom called? What kinds of atoms might have fewer than eight electrons when they make compounds, and why? Give an example. AND What kinds of atoms might have more than eight electrons when they make...
In a covalent bond, a pair of electrons often called the is responsible for holding two atoms together. What are three ways to tell if a compound is either made of ionic or covalent bonds? What term matches the following description? A covalent bond formed between two different atoms ...
If any matter is smaller or larger than an atom, it is not an atom. Molecules and compounds may contain atoms, but they are not atoms themselves. Some examples of molecules and compounds are salt water (NaCl) and ethanol. Electrically charged atoms that conduct electricity are called ions, ...
Everything, including ourselves, is made of atoms. Nuclear radiations affect humans and other life forms by interacting with these atoms. If we are to understand how radiation acts, we must first know something about the atoms themselves. What are atoms, and how do they behave?

What is dark matter made of? Despite decades of study, scientists still don't know exactly what dark matter is made of. They do know it's not made of ordinary atoms — the same kind of matter that makes up stars, planets, and people. That kind of matter is called "baryonic," and ...
What are the parts of an atom?Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around...
Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes ...
