The center of an Atom is called the Nucleus.
Explanation:
It's C, the amount of protons in the nucleus of each atom :)
Metallic ion because the metallic ions will enter an exited state and release photons energy, in the form of light, as they return to their ground state.
We need to find the Ka value of HF. First, set up the balanced chemical equation:
HF ===> H+ + F-
The formula for the Ka value of an acid is
Ka = [concentration of products] / [concentration of reactants]
Ka = [H+] [F-} / [HF]
So if we are given the concentration of the products and reactants, we will be able to solve for the Ka value of HF.
