Question

oxygen
symbol:_________________________
no. of electrons: ____________
atomic number: ____________
atomic mass: ____________

Explanation:

Oxygen is a chemical element. In the periodic table, the symbol for oxygen is \(O\). The atomic number of an element is equal to the number of protons in its nucleus, and for a neutral atom, it is also equal to the number of electrons. Oxygen has an atomic number of \(8\), so it has \(8\) electrons. The atomic mass (also known as atomic weight) of oxygen is approximately \(16\) (the average atomic mass considering its isotopes, with \(^{16}O\) being the most common isotope).

Answer:

Symbol: \(O\)
No. of Electrons: \(8\)
Atomic Number: \(8\)
Atomic Mass: \(16\)
