how many protons and electrons are in na+?
3464
There are 10 electrons present in Na+. The atom of sodium has 11 electrons, 11 protons along with 12 neutrons, but Na+ contains one less electron, 11 protons along with 12 neutrons, as the ion has lost 1 electron.

Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons. Sodium atoms have 11 electrons. Two of these are in the lowest energy level, eight are in the second energy level and then one electron is in the third energy level.

Negative ions are known as anions and have more electrons than protons. I (iodine) atoms (atomic number 53) have 53 protons and 53 electrons. I– (iodide) ions have 53 protons and 54 electrons. The composition of the nucleus for both cations and anions is the same as the corresponding atom.

The element sodium is made up of all atoms with 11 protons. How many protons, electrons, and neutrons are in a sodium-23 atom? Since all sodium atoms have 11 protons, this one has 11 protons. This tells us that it also has 11 electrons.
593866
Mass number This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).

There are 4 protons, 5 neutrons, and 4 electrons. This is a neutral beryllium atom. There are 6 protons in accordance with the proton number in the subscript. There are 6 electrons because the atom is neutral.

The sulfur has 16 electrons and 16 protons. But the ionic atom's electron quantity changes depending on how many it has gained. 'S2-' has gained 2 electrons, which means it has now 18 electrons and 16 protons.
21861
Neutral sodium has 11 electrons. To achieve a single positive charge, the neutral atom must lose one electron.
757844
We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.

It is classified as an alkali metal. Potassium atoms have 19 electrons and 19 protons with one valence electron in the outer shell. Potassium is considered chemically similar to sodium, the alkali metal above it on the periodic table. Under standard conditions potassium is a soft silvery-white metal.

Explanation: Boron has 5 protons, 5 neutrons and 5 electrons. The atomic number (also known as the proton number) of Boron is 5 as it has 5 protons. It has a mass number of 10, as protons and neutron have a relative atomic mass of 1 each, and a neutral charge, as there are equal numbers of +1 protons and −1 electrons.

Explanation: Rb atom has 37 electrons and 37 protons. when 1 electron is removed number of protons remains 37 but number of electrons is 36.36 negative charges is balanced by 36 positive charges. one extra proton is present so 1 positive charge.
