Atom and Periodic Table Review

What is the definition of Malleable?

• Can be stretched into thin wire

• A thing that is composed of two separate elements

• Can be pounded into a flat shape

• Negative ions gain electrons

What is the definition of Group?

• A table of the chemical elements arranged by atomic number

• All elements in a row that have the same number of electron shells (energy levels)

• Model that represents valence electrons

• Set of elements occupying a column in the periodic table and having broadly similar properties due to similar electon structure.

What is the definition of Ductile?

• Can be pounded into a flat shape

• A table of the chemical elements arranged in order of atomic number

• A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound

• Can be stretched into wire

Define Molecule

• A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound

• Negative ions gain electrons

• Model that represents the valence electrons

• A thing that is composed of two or more separate elements; a mixture.
