Show Your Understanding Atoms of the two elements magnesium and oxygen often combine to form a compound,
magnesium oxide. Explain how this happens, include the following information in your answer.
The number of protons and electrons of each element
How the elements become cations or anions
How the electrons are rearranged during the bonding process
How each element is made stable as a result of the bond

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
