Chem4Kids.com: Atoms


... way that words are groups of letters. An "A" will always be an "A" no matter what word it is in. A sodium (Na) atom will always be a sodium atom no matter what compound it is in. While the atoms have different masses and organization for ...

Chem4Kids.com: Atoms: Structure


... Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus . They group together in the center of the atom. That's all you have to remember. Three easy pieces! There ...

Chem4Kids.com: Atoms: Ions


... a proton number , tells you the number of protons or positive particles in an atom . A normal atom has a neutral charge with equal numbers of positive and negative particles. That means an atom with a neutral charge is one where the number ...

Chem4Kids.com: Atoms: Electrons


... is one type of bonding called electrovalent bonding (ionic), where an electron from one atom is transferred to another atom. You wind up creating two ions as one atom loses an electron and one gains one. The second type of bonding is ...

Chem4Kids.com: Atoms: Isotopes


... that ions are atoms that are either missing or have extra electrons . Let's say an atom is missing a neutron or has an extra neutron . That type of atom is called an isotope . An atom is still the same element if it is missing an ...

Chem4Kids.com: Atoms: Compounds


... molecule (O 2 ) is a good example of a molecule with a covalent bond. Ionic bonds occur when electrons are donated from one atom to another. Table salt (NaCl) is a common ex-ample of a compound with an ionic bond. You may also learn about a ...

Chem4Kids.com: Atoms: Orbitals


... Atoms: Orbitals Always in Motion As you know, electrons are always moving. They spin very quickly around the nucleus of an atom . As the electrons zip around, they can move in any direction, as long as they stay in their shell . Any ...

Chem4Kids.com: Atoms: Chemical Bonding


... make an ionic bond (also called electrovalent bond). So, let’s say we've got a sodium atom that has an extra electron. We've also got a fluorine atom that is looking for one. When they work together, they can both wind up happy! ...

Chem4Kids.com: Atoms: Advanced Ideas


... you about antimatter . It's not just found in television shows. Scientists have proved that it is real. While a regular atom has positive and neutral pieces (protons/neutrons) in the nucleus and negative pieces in orbiting clouds ( ...

Chem4Kids.com: Atoms: Neutrons


... aren't important. Every piece of an atom has huge importance to the way the atom acts and behaves. Neutrons are no exception. So, if an atom has equal numbers of electrons and protons, the charges cancel each other out and the atom has ...
