Answer:
Fluorine.
Explanation:
Fluorine has more protons resulting in a greater nuclear charge, causing a greater attraction for electrons. ... Fluorine has a smaller radius than lithium because of the greater positive charge of the nucleus, pulling electrons and the electron shells in closer.
Answer:
In simple terms, this law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of the mass of reacting mixture and the products formed remains constant.

Answer:
Ammonia is a weak electrolyte, weak base.
Option e.
Explanation:
Ammonia can take a proton from water to make ammonium.
It is a base, because it takes proton.
When a compound can take protons, we know that is base, according to Bronsted Lowry theory.
We can't describe ammonia as a base, according to Arrhenius, but we know it is base according to Lewis, because the N from the ammonia can be a donor of its electron pair.
It is weak because an small amount of ammonia, can react to produce ammonium, between the protons of water. This is the equilibrium, where the ammonia is considered as the conjugate strong acid of ammonia.
NH₃ + H₂O ⇄ NH₄⁺ + OH⁻ Kb
All the amines are considered as weak bases, because they look like ammonia, where the H of NH₃ are replaced by others chains.
------NH₂
-----NH-----
