WebThus, all atoms of this element have 38 protons and 38 electrons. The strontium-90 isotope has 90 –38 = 52 neutrons. Solution (a)Magnesium has atomic number 12, so all atoms of magnesium contain 12 protons and 12 electrons. WebThe atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a nitrogen atom has seven protons and seven electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons.

How Many Protons, Neutrons, and Electrons in an Atom?

WebAnswer (1 of 3): All isotopes of fluorine have nine protons: 9 is thus its atomic number and identity as an element. To balance those nine positive charges, a neutral fluorine atom would possess the same number of electrons. Nearly all naturally-occurring fluorine is the \ _9^{19}\mathrm{F} isot... Web11 dec. 2024 · F as-written as the fluorine atom, with atomic number 9, giving it 9 protons by definition.

It has an atomic mass of 24.3 amu (atomic mass units). Protons and neutrons are 1 amu each. Electrons are close to 0 amu, and are included in the mass weight calculations. It there are 12 protons, at 1 amu each, we can subtract 12 from the atomic mass of 24.3 to get 12.3. phosphate monobasic dibasic
