Magnesium. You can count the electrons in each level and because the number of electrons is the same with protons you have the atomic number based of which you can get the element in the periodic table
Answer:
They are all the same = 8
Explanation:
Since the symbol of that atom is not give, we can infer from the given number the nature and kind of element we are dealing with.
The number 15.999 rounded up to 16 is the atomic weight of the atom also called the mass number.
Although not peculiar enough, we are certain that this atom is Oxygen.
On the periodic table, elements are arranged based on their atomic numbers.
Atomic number of oxygen = 8 = number of protons
For every neutral atom on the periodic table, the number of protons and electrons are the same
Atomic number of oxygen = number of protons = number of electrons = 8
Number of neutrons = Mass number - atomic number = 16 - 8 = 8
First of all, it is a nucleic acid, not nuclear acid.
Examples are DNA and RNA( Deoxyribonucleic Acid and Ribonucleic Acid)
