Twelve: 6 electrons in 2p6 and 6 electrons in 3p6. No electrons in 4p orbital in ground state, so 4p0, only 4s1 is occupied (4th period, group 1)
An atom of oxygen has 2 energy levels that are occupied - the first energy level (K shell) can hold up to 2 electrons, and the second energy level (L shell) can hold up to 6 electrons. Oxygen has a total of 8 electrons.
The K shell of an atom can hold up to 2 electrons.
One atom of potassium contains 19 protons.
A neutral atom of calcium has five energy levels that are partially or fully occupied. These energy levels are filled with electrons according to the Aufbau principle, with the first two levels (K and L) being fully filled while the remaining three levels (M, N, and O) are partially filled.
Potassium (K) is an alkali metal whose atoms have one valence electron. The atomic number of K is 19, which means its atoms have 19 protons in their nuclei. A neutral K atom also has 19 electrons. An atom of K will lose its single valence electron to become a K+ cation. Therefore, there are 18 electrons in a K+ cation.

There are two atoms in one molecule KBr. One atom of potassium (K) and one atom of bromine (Br).
Potassium atom has 1 valence electron
Ammonia is a molecule (NH3) and not an atom.
A neutral potassium atom has 19 electrons in total and 1 valence electron.
If the K and L shells of an atom are full, the atom will have 18 electrons. The K shell can hold 2 electrons and the L shell can hold 8 electrons, totaling 10 electrons in both shells. Therefore, if both the K and L shells are full, there will be 18 electrons in the atom.
This is an ionic bond and electrons are donated from the K atom to the Iodine atom
