if you are asking about ICl4- ion then there are 28 valence electrons and 8 binding ones.total of 36 electrons
The valence electrons are the electrons in the last shell or energy level of an atom. They do show a repeating or periodic pattern. The valence electrons increase in number as you go across a period. Then when you start the new period, the number drops back down to one and starts increasing again.1A2A3B4B5B6B7B------8B------1A2A3A4A5A6A7A8AH1He2*Li1Be2B3C4N5O6F7Ne8Na1Ar8K1Sc3Ti4V5Cr6Mn7Fe8Co8Ni8Cu1Zn2Kr8For example, when you go across the table from carbon to nitrogen to oxygen, the number of valence electrons increases from 4 to 5 to 6. As we go from fluorine to neon to sodium, the number of valence electrons increases from 7 to 8 and then drops down to 1 when we start the new period with sodium. Within a group--starting with carbon and going down to silicon and germanium--the number of valence electrons stays the same.Every electron that's a valence electron in an atom is also a valence electron in a molecule formed by that atom. For example, an atom of carbon has 4 valence electrons. That means the carbon atom in carbon dioxide CO2 must contribute 4 valence electrons to the carbon dioxide molecule.An electron that is added to or subtracted from a molecule to make a polyatomic ion is assumed to be a valence electron.These facts let you count the valence electrons in the N2[CH3]42+ion in two steps:Add up the valence electrons from each atom that forms the molecule.Sometimes it helps to write the simplest form of the chemical formula vertically while you do this:N22 x 5 = 10( 2 nitrogen atoms, each with 5 valence electrons )C44 x 4 =16( 4 carbon atoms, each with 4 valence electrons )H1212 x 1 = 12( 12 hydrogen atoms, each with 1 valence electron )38total valence electrons from the atomsAdd or subtract valence electrons to account for the charge on the molecule.For example, if the molecule has a charge of -1, add 1 valence electron. If the molecule has a charge of -2, add 2 valence electrons. On the other hand, if the molecule has a charge of +1 , subtract 1 valence electron, and if the molecule has a charge of +2, subtract 2 valence electrons.In this case, since the N2[CH3]42+ion has a charge of +2 we need to subtract 2 valence electrons , for a new total of 36 valence electrons.
The neutral atom of molybdenum has 42 electrons.
42 electrons
It has 3 more protons than electrons. Protons are 1+ and electrons are 1-. So the charge on the hypothetical ion would be 3+

BF3 has 24 valence electrons.

(6)====Molybdenum is within group 16. If in group 1 then it has 1, if group 2 then it has 2. If in the teens, drop the 1. So this element is in group 16 so it has 6 valence electrons. Try Chlorine- notice it is in group 17 so it has 7 v electrons.
The neutral atom of molybdenum has 42 electrons.
42 electrons
It has 3 more protons than electrons. Protons are 1+ and electrons are 1-. So the charge on the hypothetical ion would be 3+
[Kr]4d6 ion has 42 electrons. As it is a 3+ ion, the parent atom would have 45 electrons. This would make it Rhodium Rh.
If 42 is the atomic number then there is 42 electrons in isotope.
Molybdenum is the element that has 42 electrons.
If the charge is positive number of electron will be 40, if the charge is negative it will be 44.As molybdenum has atomic number 42.
