there are 11 of them.
Sodium is a metal element. There are 11 electrons in a single atom.
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
Na
Sodium loses one electron to form a Na+ ion. Sulfur gains two electrons to form a sulfide ion, S2-.
An ion. Eg Na atom loses one electron to become Na+
There are 11 electrons orbiting around Na atom, cuz its atomic number is 11.
This is not an atom. This is an ion. This is Na+ ion.
Na is the chemical symbol for Sodium. Na charged is an ion, meaning the number of electrons in the atom differs relative to the charge; for instance, Na+ is missing one of its valence electrons and Na- has an additional electron.
Sodium (Na) has a total of 11 electrons in the neutral atom. 1 of these is considered a valence electron, and the other 10 are considered core electrons.See the Related Questions for more information.
A sodium (Na) atom is neither an ion nor a molecule. It is a single, neutral atom with 11 protons in its nucleus and 11 electrons orbiting around it. An ion is when an atom gains or loses electrons to become charged, and a molecule is a combination of atoms bonded together.
surely i don't know sodium atom which can be gained 2 electrons but anyway i thought the answer is Na+2
The cation of sodium has 11 protons and 10 electrons.
