A nucleus having 11 protons and 12 neutrons is a sodium nucleus, no of neutrons may differ in case of isotopes.
There are 11 protons in a sodium nucleus.
12
It would be more difficult to remove an electron from bromine than from sodium because bromine's valence electron is farther from the nucleus, experiencing weaker attraction compared to sodium's valence electron, which is closer to the nucleus.
Sodium is an element itself, it has no elements inside.
The term nucleus is used to describe the center of something, usually an atom or a cell; it could be used to describe the center of a city as well.
Sodium has 11 protons and usually 12 neutrons in its nucleus, giving it an atomic mass of 23 units. The nucleus of sodium can also have isotopes with different numbers of neutrons, such as sodium-22 and sodium-24.
Sodium has 12 neutrons; all neutrons are neutral particles.
The nucleus of sodium has a greater pull on the electron in the outer shell compared to the nucleus of neon. This is because sodium has one less electron in its outer shell than neon, resulting in a stronger attraction between the nucleus and the remaining electron in sodium.
For sure the sodium atomic nucleus contains 11 protons. The natural isotope of sodium(23) also contains 12 neutrons, but other isotopes are possible with less or more of them in the nucleus. Still 11 protons, always!
It would become an isotope. Isotopes have different numbers of neutrons.
11. The atomic number of any atom equals the number of protons in the atom.
there are 123 electrons and 67 nucleus
