Part B What is the symbol of the atom obtained by adding one proton to 19F?
Express your answer as an isotope

Neon

Explanation:

A proton is the positively charged particle in the atom. The atomic number of an atom is the number of protons present in the atom while the mass number of an atom is the sum of the number of protons and neutrons in the nucleus of an atom.

If an extra proton is added to 19F, then neon is formed.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
