Non of them seem right... but I think C could be correct cause it definitely cant be A.
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.
Alpha decay represents the forceful ejection of two protons and two neutrons from the nucleus of the parent atom. If 214 Po undergoes alpha decay, the equation would be:
214 Po ➡️ 210 Pb + 4 He + energy
Alpha decay is in the form of a helium nucleus, two protons and two neutrons.
Answer:
H⁺(aq) + OH⁻(aq) ⇒ H₂O(l)
Explanation:
Let's consider the molecular equation that occurs when aqueous solutions of perchloric acid and potassium hydroxide are combined. This is a neutralization reaction.
HClO₄(aq) + KOH(aq) ⇒ KClO₄(aq) + H₂O(l)
The complete ionic equation includes all the ions and molecular species.
H⁺(aq) + ClO₄⁻(aq) + K⁺(aq) + OH⁻(aq) ⇒ K⁺(aq) + ClO₄⁻(aq) + H₂O(l)
The net ionic equation includes only the ions that participate in the reaction and the molecular species.
H⁺(aq) + OH⁻(aq) ⇒ H₂O(l)
The Universe
Is Not shrinking
Is Not Expanding
It Does contain billions of galaxies
And it is Not about 10 billion years old
Hope this Helps. :)
