Chromium's atomic number is 24. A neutral atom of chromium would thus have 24 protons and 24 electrons. Since we're dealing with Cr3+, though, we need to subtract 3 electrons from this number, giving us 21.

∙ 14y agoIn Cr+3 ion there are only three electrons because during oxidation one from 4s orbital and two from 3d orbitals have been lost.

How many electrons are in the d orbital of Os3 plus?
There are 5 electrons in the d orbital of an Os3+ ion.
How the atomic number related to the core electrons?
For a neutral (uncharged) atom, the total number of electrons is equal to the atomic number (number of protons). This would be the sum of the core electrons plus the valence electrons.
What is the total number of electrons in an Pb plus 4?
Pb which is neutral has 82 electrons. Thus, if it has a 4+ charge, then it has 78 electrons.
How many electrons are in the outer shell of aluminium?
3 electrons total. electrons is the number on the top right corner with the plus sign indicating that electrons are positive.
What is the total number of valence electrons in the Lewis structure of PBr4 plus?
For PBr4^+ you have...Valence electrons in P = 5Valence electrons is Br = 7 and there are 4 of them so total = 28This gives a total of 33, but you subtract 1 because of the + charge on the ion,Thus total valence electrons shown in the Lewis dot will be 32.
How many electrons are in the d orbital of Os3 plus?
There are 5 electrons in the d orbital of an Os3+ ion.
What is the total number of electrons present in an Mg 2 plus cation?
The Mg2 plus cation has 10 electrons.

3 electrons total. electrons is the number on the top right corner with the plus sign indicating that electrons are positive.
The atomic mass of an atom is determined by the combined masses of its what?
The total number of protons plus the total number of neutrons
Difference between Na and Na plus?
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
What is the electron configuration of niobium 2 plus?
It has 39 electrons and ends in a d orbital. Now finish your homework :)
What is the total number of valence electrons in the Lewis structure of PBr4 plus?
For PBr4^+ you have...Valence electrons in P = 5Valence electrons is Br = 7 and there are 4 of them so total = 28This gives a total of 33, but you subtract 1 because of the + charge on the ion,Thus total valence electrons shown in the Lewis dot will be 32.
What species has the greatest number of electrons I- or Cu2 plus or Fe3 plus or Au or Hg?
Hg will have 80 electrons.
How many electrons are in a sodium cation Na plus?
The number of electrons is 10.
What is the total number of electrons in an Al3 plus ion?
Well, Al is Aluminium, which is 13. 13 + 3 is 16.
