What is the explanation of the atomic mass of Sodium?
Sodium is a meta element. Atomic mass of it is 23. Atomic number of it is 11.
How many neutron in sodium element?
Subtract the atomic # from the atomic mass. Atomic number = number of Protons. Atomic mass = total nucleons (Protons + Neutrons).Atomic # = 11 and Atomic Mass = 23. So 23-11 = 12 Neutrons.
If element Q has 11 protons its atomic what is 11?
If an element has 11 protons, its atomic number is 11.
What ids Boron's mass number?
Boron is a non metal element. Atomic mass of it is 11.
What is the atomic number and atomic mass of Sodium?
The atomic number of Sodium is 11, which means it has 11 protons in its nucleus. The atomic mass of Sodium is approximately 23 amu (atomic mass units), which is the weighted average of all the isotopes of Sodium found in nature.
What element in period 2 has a atomic mass of 11?
Short answer: boron. Long answer: any element with 11 protons or less could theoretically have an atomic mass of 11, as the mass = Number of Protons + Neutrons, if you add/take a certain number of neutrons from the atom it will be able to have an atomic mass of 11, but some aren't possible and others are too unstable, and will decay instantly.
Which element has an atomic mass of11?
Atomic mass numbers are not properties of elements overall, but only of particular isotopes of elements. The only stable element with an isotope with mass number 11 is boron. Beryllium and carbon also have isotopes with mass number 11, but these are radioactive.
What is the atomic number and the mass number of an atom of an element with 11 protons and 12 neutrons?
Atomic number: 11 Mass number: 23 (11 protons + 12 neutrons) Atomic mass (aka atomic weight): 22.98976928 Element: Sodium (sodium-23 is the only stable sodium isotope)
Which element has mass number of 23?
Sodium is a metal element. Atomic mass of it is 23.
What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
Boron has an atomic mass of 11 and an atomic number of 5 so the number of neutrons must be?
The number of neutrons in an atom is calculated by subtracting the atomic number from the atomic mass. In this case, for boron with an atomic mass of 11 and atomic number of 5, the number of neutrons would be 6.
What is the mass number of boron 11?
Boron is a non metal element. Atomic mass number of it is 11.
