What types of atoms typically form covalent bonds? What is a type of chemical bond involving the sharing of electrons between atoms in a molecule, especially the sharing of a pair of electrons by two adjacent atoms? Which atom is most likely to form three covalent bonds? (a) Si (b...
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...
Each electron has a charge of -1 (that is, they are negatively charged). Electrons are distributed around the volume of the atom of which they are a part in 'shells', 'orbits' or 'energy levels', which are all different terms used to describe the electronic structure of atoms, an impo...
Atoms have great variations in weight, although they are all about the same size. The diameter of an atom is a million times smaller than one strand of thick human hair, very tiny indeed. The diameters of atoms range from approximately 0.1 to 0.5 nanometers. For example, plutonium, which ...
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 a group of atoms joined together called? What do atoms form when they share electron pairs? What kind of bond holds together atoms within a molecule? If a molecule is composed of atoms that pull on electrons with the same strength, the molecule will be ___. What is the common...

But if you had a few dozen different types of atom, you could build all these things and more: you'd just join the atoms together in different ways. Atoms are the tiny building blocks from which everything around us is constructed. It's amazing to think you can make anything out of ...
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 ...
