100
an electron that is found in the outermost shell of an atom.
What is a valence electron?
100
electrons are transferred from one atom to another atom
How do ionic bonds form?
100
forms when atoms share electrons.
What is a covalent bond?
100
a bond formed by the attraction between positively charged metal ions and the electrons around them.
What is a metallic bond?
100
a group of atoms that are held together by chemical forces
What is a molecule?
200
1
How many valence electrons are there in group one?
200
lose electrons
What is a positive ion?
200
the electrons move freely around the metal ions.
How can metals be reshaped?
200
a model that shows only valence electrons in an atom
What is an electron-dot diagram?
300
7
How many valence electrons are there in group 17?
300
gain electrons
What is a negative ion?
300
the ability to be drawn into wires
What is ductility?
300
electron-dot diagram
What is one way to represent molecules?
400
gaining, losing, or sharing electrons
How do atoms bond?
400
the resulting compound has different properties than the metal and nonmetal did.
What happens when a metal and a nonmetal combine be ionic bonding?
400
the ability to be rolled or pounded
What is malleability?
400
molecules made up of two atoms
What is a diatomic molecule?
500
similar properties
How are elements grouped?
500
Ionic compounds form solids by building up a repeating pattern.
What is crystal lattice?
500
electrical conductivity, ductility, and malleability.
What are the properties of metals?
500
predict how atoms might bond
