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.
Dubnium has 105 electrons.
Potassium (K) contains 19 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).
An atom of xenon contains 54 electrons, the atomic number of xenon.
Boron is an atom or element, and it contains protons, electrons, and neutrons.
Dubnium has 105 electrons.
Potassium (K) contains 19 electrons.
Magnesium atoms have 12 electrons.
Vanadium (V) contains 5 electrons in its 3d orbitals.
The element that contains only two 2p electrons is helium.
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.
Element #105 is called Dubnium.
