Question 74

Characteristics of alkali metals

Answer 74

• low ionization energy (easy to remove electrons)
• very reactive with water
• readily form ionic compounds

Question 75

What happens when alkali metals react with water

Answer 75

ex. M + H20 -> MOH + 1/2 H2

- very exothermic reaction, produces hydrogen gas

Question 76

What are alkali metals

Answer 76

the first group/column of the periodic table

Question 77

What are alkaline earth metals

Answer 77

the second group/column of the periodic table

Question 78

Characteristics of alkaline earth metals

Answer 78

• low (but not as low as alkali) ionization energy
• reactive with water (but not as much as alkali)
• generally more reactive with water as you move down the group

Question 79

What are the halogens

Answer 79

group/column 7A/17

Question 80

Characteristics pf halogens

Answer 80

• very electronegative with high electron affinity
• only 1 valence electron away from a full octet
• easily reduced (electrons added to it)
• highly reactive with metals, and are good oxidizing agents (take electrons)

Question 81

What are the noble gases

Answer 81

group/column 8A/18

Question 82

Characteristics of the noble gases

Answer 82

-inert, unreactive because they already have a full octet

Question 83

What are the transition metals

Answer 83

d block elements

Question 84

Characteristics of transition metals

Answer 84

• form brightly-colored compounds due to the unique shape of d orbitals which allow their electrons to absorb colored light and be promoted to higher energy levels
• can have multiple oxidation states

Question 85

What is the oxygen group?

Answer 85

Group/column 6A/16

Question 86

Characteristics of the oxygen group

Answer 86

• two forms of molecular oxygen: O2 and O3
• O2 is a good oxidizing agent (oxidant)
• O3 is an even better oxidizing agent
• metals react with oxygen to for metal oxides
• M + O2 -> MO
