Answer 9

An atom that has gained or lost 1 or more electrons and has a - or + charge

Question 10

Ionic bond

Answer 10

The transfer of 1 or more electrons between atoms

Question 11

Ionization energy

Answer 11

Removing an electron from an atom or ion

Question 12

Isotope

Answer 12

2 or more forms of the same element that contains an equal number of protons but different number of neutrons

Question 13

Chemical properties

Answer 13

Identified by a chemical change

Question 14

Nucleus

Answer 14

The center of an atom

Question 15

Orbit

Answer 15

The fixed path on which electrons moves or revolves around the atoms nucleus

Question 16

Atom

Answer 16

A particle that consists of a nucleus with protons electrons and neutrons orbiting it

Question 17

How are ionic compounds created

Answer 17

They are created by a metal and non metal (cation and anion) transferring electrons

Question 18

How are covalent compounds created

Answer 18

They are created by 2 non metals (anions) sharing electrons

Question 19

What happens to electrons of each element when ionic bonds are created

Answer 19

The metal loses electrons to become a cation and the non metal gains the electrons to become an anion

Question 20

What happens to electrons of each element when covalent bonds are created

Answer 20

The electrons go to the nucleus of both atoms and both elements share the electrons

Question 21

Molecule

Answer 21

A group of atoms bonded together

Question 22

Shell

Answer 22

The outside part of an atom around the atomic nucleus
