potassium
The element that contains 105 electrons is fermium, which has an atomic number of 100. This means it has 100 protons and, in a neutral atom, 100 electrons.
Potassium is an element with the atomic number 19, meaning it has 19 protons in its nucleus. Therefore, a single atom of potassium contains 19 protons along with neutrons and electrons.
The element with 32 electrons is Germanium. Its atomic number is 32, which means it has 32 protons (and thus 32 electrons when neutral).
In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).
19 electrons, 19 protons and 20 neutrons
The element that contains 105 electrons is fermium, which has an atomic number of 100. This means it has 100 protons and, in a neutral atom, 100 electrons.
Magnesium atoms have 12 electrons.
Vanadium (V) contains 5 electrons in its 3d orbitals.
Potassium is an element with the atomic number 19, meaning it has 19 protons in its nucleus. Therefore, a single atom of potassium contains 19 protons along with neutrons and electrons.
The element that contains only two 2p electrons is helium.
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
This is an artificially prepared isotope of phosphorus, P-30.

molybdenum
The element with 32 electrons is Germanium. Its atomic number is 32, which means it has 32 protons (and thus 32 electrons when neutral).
Iron is the industrially important element that contains 26 electrons and rusts in the presence of air and moisture.
The 19th element is potassium, which has the atomic symbol K. It has 19 electrons, including one valence electron that can be easily lost.
