Question

a repetition of properties occurs when elements are arranged in order of increasing atomic number is called? electronegativity periodicity element type that is a good conductor of heat and electric current? non - metal metal

Explanation:

1. When elements are arranged in order of increasing atomic number, the repetition of properties is called periodicity. Electronegativity is the ability of an atom to attract electrons in a chemical bond.
2. Metals are good conductors of heat and electric - current. Non - metals are generally poor conductors of heat and electricity.

Answer:

1. periodicity
2. Metal
