Answer:There are 18 electrons and 17 protons, so the chlorine atom has become a charged chlorine ion with a charge of negative one (-1). ... When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level.

Answer:
Over ninety percent of all the atoms in the Universe are hydrogen atoms.
Explanation:
Over ninety percent of all the atoms in the Universe are hydrogen atoms. By mass, hydrogen makes up about 75% of all matter in the Universe. Hydrogen atoms are also the smallest and lightest of all the atoms with only one electron and one proton in a common single hydrogen atom (called protium).
Answer:
HNO3(aq) + OH-(aq) → NO3-(aq) + H2O(l)
Explanation:
According to Bronsted-Lowry theory, an acid is a substance that donates a proton (H+) and produces a conjugate base while a base is a molecule or ion which accepts the proton.
An example of Bronsted-Lowry acid and base is Nitric acid, HNO3 and hydroxide ion, OH- respectively as shown in the given reaction.
Thus, the nitric acid acts as an acid by donating a proton to the hydroxide ion which accepts it, thus producing nitrate ion, NO3- as a conjugate base, while OH- produces H2O as a conjugate acid.
