An atom has three types of very tiny particles called protons, neutrons and electrons. The center of an atom is called the nucleus, and it is made up of protons and neutrons. The electrons in an atom fly around and above the nucleus in a cloud-like formation. The protons have a positiv...

A helium atom has two protons and two electrons. 1 Molecule The result of atomic interactions and bonding. DNA molecules carry genetic information. 3 Atom An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutra...
An atom has 75 protons, 74 electrons, and 112 neutrons. What is the charge of the atom? What are protons, electrons, and neutrons? What will an atom do if it has 1 to 3 valence electrons? How many protons, neutrons, and electrons are in a neutral atom of sodium?
Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus. The electron cloud has a radius 10,000 times greater than the nucleus, according to theLos Alamos National Laborat...
Valence Electrons:Valence electrons in an atom are the electrons (normally in the outermost shell) that can be shared or transferred to form bonds. In fact, in an atom, the inner electrons (beyond the outermost shell) are unusable and do not directly determine the chemistry of th...
