Only two electrons.
Sulfur has 6 electrons in its outermost energy level.
Atomic number 10 corresponds to neon. Neon has 10 electrons, with 2 electrons in the innermost energy level and 8 electrons in the outermost energy level.
A neutral atom with an atomic number of 15 (phosphorus) will have 5 electrons in its outermost energy level. This is because the atomic number tells us the number of protons, which is equal to the number of electrons in a neutral atom. The outermost energy level for phosphorus is the third energy level.
valance
Fermium has 100 protons and electrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of fermium is 100; but fermium has 17 isotopes, each with a different number of neutrons. For the most stable isotope of fermium, 257Fm: protons-100 electrons-100 neutrons-157 atomic mass per unit (AMU)-257
Electrons in the outermost energy level are called valence electrons. The number of valence electrons on an atom largely determine its behavior and characteristics.
The principal quantum number for the outermost electrons in a Bromine atom in the ground state is 4. This is because the outermost electrons of an atom are located in the highest energy level, and for Bromine (with 35 electrons), the outermost electrons are in the 4th energy level.
the outermost electrons are known as the "valence electrons"
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
Fermium has seven electron shells.
The atoms of fermium have 100 protons each.
5, it is the number of valance electrons determined by the roman numeral over the group in the periodic table of elements
