Answer:
isotopes
Explanation:
isotopes of the elements where the nucleas is unstable generally releases nuclear radiation.
The answer is sodium
Sodium has 11 protons (atomic number is 11) and has one valence electron. As the Bohr model diagram below shows, Sodium has 11 protons and 12 neutrons<span> in the nucleus to make the mass number 23. The 11 electrons necessary to make Sodium neutral (protons = electrons) are arranged in a pattern of 2-8-1.</span>

<span>In this item, we are asked to calculate for the mass of 22.05 mole of octane given that its molecular mass is equal to 114.22 g/mol. To answer this item, we simply have to multiply the number of moles with the molecular mass. That is, (114.22 g/mol)(22.05 mol) which is equal to 2518.221 grams. </span>
