An atom of fluorine would possess 7 valence electrons as it is found in group 7 of the periodic table.
The group number in this case corresponds to the number of valence electrons present.
So, for instance, because Chlorine is also found in group 7, it would also have 7 valence electrons.
Answer:
B Sharing electrons
Explanation:
That is the right answer.
Covalent bonds are formed by the sharing of electrons while ionic Bonds are formed by the transfer of electrons between a metal and a non metal.

Moles of Sulfuric acid- H₂SO₄ needed to react completely : 3.2 moles
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction(balanced)
<em>2LiOH + H₂SO₄ → Li₂SO₄ + 2H₂O</em>
From the reaction equation above, the reaction coefficient shows the mole ratio of reagents and products
moles of Lithium hydroxide-LiOH = 6.4 moles
mol ratio of LiOH : H₂SO₄ = 2 : 1, so mol H₂SO₄ :

Answer:
D. Waste management issues
Explanation:
Answer A: The five major types of pollution - water pollution, air pollution, land pollution, light pollution, noise pollution - have negative effects on the environment, on human health, and our planet as a whole.
Answer B: Urban Heat Island (UHI) is an urban area that is significantly warmer than its surrounding rural areas due to human activities. UHI decreases air quality.
Answer C: The increased use of surrounding land is the main cause of biodiversity loss.
Answer D: Any field of environmental management help people to solve pollution problems. So, D is the correct answer.
