Front (Question)

• What can link two atoms together?

Back (Answer)

a bond

Front (Question)

• What is an ion?

Back (Answer)

an atom that is charged because it has lost or gained one or more electrons

Front (Question)

• What happens when an ionic bond is formed?

Back (Answer)

One atom loses electrons to another atom to form oppositely charged ions that attract each other.

Front (Question)

• Which kinds of elements are usually involved in the formation of ionic bonds?

Back (Answer)

metals and non-metals

Front (Question)

• How is a positive ion formed and what is it called?

Back (Answer)

formed by the loss of electrons; cation

Front (Question)

• How is a negative ion formed and what is it called?

Back (Answer)

formed by the gain of electrons; anion

Front (Question)

• Why do atoms form ions?

Back (Answer)

to become more stable (like a noble gas)

Front (Question)

• What is the charge on the ions of elements in group 1 of the periodic table?

Back (Answer)

Front (Question)

• What is the charge on the ions of elements in group 6 of the periodic table?

Back (Answer)

-2

#10

Front (Question)

• What happens to the electrons in the outer shell of metal atoms when they form ions?

Back (Answer)

they are lost

#11

Front (Question)

• What is the name of the ionic compound containing calcium and bromine only?

Back (Answer)

calcium bromide

#12

Front (Question)

• How many electrons are in the outer shell of the elements in groups 5, 6 and 7?

Back (Answer)

5, 6 and 7

#13

Front (Question)

• What kind of electron arrangement is most stable?

Back (Answer)

a complete/full outer shell

#14

Front (Question)

• What are molecules?

Back (Answer)

groups of atoms held together by (covalent) bonds

#15

Front (Question)

• Which type of atoms are covalent bonds found between

Back (Answer)

non-metal and non-metal

#16

Front (Question)

• What happens to electrons between two atoms in a covalent bond

Back (Answer)

they are shared

#17

Front (Question)

• What kinds of elements usually form molecules?

Back (Answer)

non-metals

#18

Front (Question)

• What is the name of the force that holds molecules together in gases and liquids

Back (Answer)

intermolecular force

#19

Front (Question)

• How strong are the forces of attraction between molecules compared to the bonds within molecules?

Back (Answer)

They are relatively weak.

#20

Front (Question)

• Are simple molecules usually good conductors of electricity at room temperature?

Back (Answer)

No, they are poor conductors of electricity.

#21

Front (Question)

• What are intermolecular forces?

Back (Answer)

forces of attraction between molecules

#22

Front (Question)

• Do simple molecules have strong intermolecular forces between them?

Back (Answer)

No. They are described as weak.

#23

Front (Question)

• Why are simple molecules poor conductors of electricity?

Back (Answer)

There are no charge carriers.

#24

Front (Question)
