• A reaction where a more reactive element replaces a less reactive element in a compound.

• A reaction where two elements combine to form a compound.

• A reaction where an element dissolves in a liquid.

Multiple Select

Select all elements that are halogens from the following list: chlorine, magnesium, lithium, potassium, bromine, calcium, iodine.

• chlorine

• bromine

• iodine

• magnesium

Multiple Choice

What happens to Group 1 and 2 atoms when they react?

• They gain outer electrons and become negative ions

• They lose their outer electrons and become stable positive ions

• They share electrons and form covalent bonds

• They remain unchanged

Multiple Choice

Which atom is from Group 7?

• a

• b

• c

Multiple Select

Select all statements that correctly describe the formation of sodium fluoride (NaF) from sodium and fluorine.

• Sodium transfers its outer electron to fluorine

• Both sodium and fluorine gain electrons

• Stable oppositely charged ions are formed

• Electrostatic attraction holds the ions together

Open Ended

Explain why potassium reacts with bromine to form potassium bromide and not potassium iodide.

Open Ended

Describe the difference between how Group 1 and Group 2 metals react with Group 7 elements to form halide salts.

Multiple Select

Which of the following are correct observations when magnesium reacts with chlorine gas?

• A bright white flame is produced

• Green, toxic, non-metallic

• Yellow, sweet-smelling, non-metallic

• Blue, toxic, metallic

Open Ended
