Complete the sentences to identify the trend in first ionization energies as one proceeds down the group 7A elements and explain

how this trend relates to the variation in atomic radii.
Complete the following sentences using this word bank:

a. increase
b. decrease
c. greater
d. smaller

1. Moving from F to I in group 7A, first ionization energies ____
2.Moving from F to I in group 7A, atomic radii ____
3. The relationship between atomic radii and first ionization energy going down a column is best explained by the fact that the greater the atomic radius, the ____ the electrostatic attraction of an outer electron for the nucleus and the ____ the ionization energy of the element.

Answer:

a)decrease

b)increase

c)smaller

d)smaller

Explanation:

Ionization energy decreases down the group due to increase in the atomic radius. The distance between the outermost electron and the nucleus increases hence the nuclear attraction for the outermost electrons become smaller and the ionization energy also become smaller as electrons are now easily removed from the outermost shell.

Hence the group of answer choices provided above.

Wear _______________________ when handling batteries, because they can explode or leak.
Basile [38]

The answer is: b. Safety glasses and acid-resistant gloves.

Battery acid (sulfuric acid) has pH = 0.

Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).

Chemical dissociation of sulfuric acid in water:  

H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).  

Sulfuric acid can come in contact with eyes and hands, so it is important to wear safety glasses and acid-resistant gloves.
