Quiz covering atoms, atomic bonding, and elements.

What is an atom?

• a particle that consists of a nucleus of protons and neutrons surrounded by an electromagnetically-bound cloud of electrons

• the membrane-enclosed organelle within a cell that contains the chromosomes

• a stable subatomic particle, symbol p , H⁺, or ¹H⁺ with a positive electric charge of +1 e. Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron.

• a subatomic particle with a negative one elementary electric charge

What is a metallic bond?

• a metal, and share outer bonds with atoms in a solid. Each atom gives off a positive charge by shedding its outer electrons, and the negatively charges electrons hold the metal atoms together.

• chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compound

• produced by the sharing of atoms and electrons

• share between covalent and oxygenated atoms

What is a covalent bond?

• share between covalent and oxygenated atoms

• produced by the sharing of atoms and electrons

• share outer bonds with atoms in a solid. Each atom gives off a positive charge by shedding its outer electrons, and the negatively charged electrons hold the metal atoms together

• Each atom gives off a positive charge by shedding its outer electrons, and the negatively charges electrons hold the metal atoms together.

• a chemical bond that involves the sharing of electrons to form electron pairs between atoms
