Atoms are neutral because they have same number of positively charged particles, protons, and negatively charged particles, electrons. The amount of charge in a single proton is equal to the amount of charge possessed by... More »

Atoms are typically found in a neutral state, which means they have an equal number of electrons and protons. Electrons are negatively charged particles while protons are positively charged. More » Science Chemistry Atoms & Molecules

Atoms lose their neutrality when electrons are either lost or gained. Atoms that have lost or gained electrons are called ions. Neutral atoms have the same number of protons, neutrons and electrons. More » Science Chemistry Atoms & Molecules

To find the number of electrons an element has, locate it on the periodic table of elements, find the atomic number, and note the number of protons; because atoms are naturally electrically neutral, the protons and elect... More »

Atoms form bonds with other atoms because of the electrostatic attraction between positively-charged protons and negatively-charged electrons. When this force of attraction brings atoms together to form substances contai... More »

Moving across periods on the periodic table from left to right, the atoms tend decrease in radius size because each atom has more protons than the atom before it, meaning there is more of an attractive force in the nucle... More »

An element is defined as a substance made up of atoms with a specific number of protons. That means that every atom with 1 proton is always a hydrogen atom. Elements cannot be broken down further by chemical means and al... More »
