Beryllium has 5 neutrons.
Yes, it is correct.
Isotope 24Na (or Na-24) has 11 protons and 13 neutrons, its mass number is 24Isotope 23Na is the stable form of Na with 11 protons, 12 neutrons and with mass number 23.
34 - 16, the atomic number of sulfur [note correct spelling] or 18.
The number of neutrons in any element is equal to mass number - atomic number. So,number of neutrons in cobalt is = 58 - 27 = 32. therefore, number of neutrons in cobalt is 32.
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
Yes, it is correct.
Yes, it is correct.
It is not correct.
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
Protons = 17; Electrons = 17; Neutrons = 19
No, The atomic mass is the number of protons plus the number of neutrons (the mass of the atom's nucleus). Note that the atomic mass is therefore different in cases where there are different isotopes of the element (because the nucleus will have a different number of neutrons for each isotope). The atomic number is the number of protons (or electrons in the atom's neutral state).
Isotope 24Na (or Na-24) has 11 protons and 13 neutrons, its mass number is 24Isotope 23Na is the stable form of Na with 11 protons, 12 neutrons and with mass number 23.
The isotope of sulfur that has 19 neutrons is sulfur-32 (S-32). This isotope has 16 protons (the atomic number of sulfur) and 19 neutrons, giving it a total mass number of 32.
The number of protons and of electrons is always 16, which is the atomic number of sulfur. The number of neutrons depends on which isotope of sulfur is the atom considered, but since the most common isotope is sulfur-32, the number of neutrons is most commonly also 16.
The correct symbol for the isotope of potassium with 22 neutrons is K-41. The number after the element symbol represents the atomic mass, which is the sum of protons and neutrons in the nucleus. In this case, potassium has 19 protons and 22 neutrons, resulting in an atomic mass of 41.
34 - 16, the atomic number of sulfur [note correct spelling] or 18.
Number of Neutrons = Mass number - Number of Protons
