5, because the charge indicates the number in the valence orbital (outer shell).
Cl- has 8 valence electrons. This is because chlorine, in its neutral state, has 7 valence electrons (group 17), and the -1 charge of the chloride ion indicates the addition of an extra electron.
There are 36 electrons in IF4-. Iodine has 7 valence electrons, and each fluorine atom contributes 7 valence electrons, totaling 35 valence electrons. The negative charge of -1 indicates an additional electron, bringing the total to 36 electrons.
Manganese has 25 electrons. Hope this helps. :)
Ethylene dication (C2H4^2+) has a total of 8 valence electrons. Each carbon atom contributes 4 valence electrons, and the four hydrogen atoms contribute 1 electron each, totaling 8. However, since the ethylene dication has a 2+ charge, it means that it has lost 2 electrons, resulting in a total of 6 valence electrons after accounting for the charge.
Zinc has two valence electrons.
Manganese has 7 valence electrons.
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
There are seven.
The CN- ion has 10 valence electrons. The carbon atom contributes 4 valence electrons, and the nitrogen atom contributes 5 valence electrons. Additionally, the negative charge adds 1 electron, resulting in a total of 10 valence electrons.
Cl- has 8 valence electrons. This is because chlorine, in its neutral state, has 7 valence electrons (group 17), and the -1 charge of the chloride ion indicates the addition of an extra electron.
The carbonate ion, CO3 2-, has a total of 24 valence electrons. This is because there are three oxygen atoms, each contributing 6 valence electrons, and a charge of 2- indicates the addition of 2 electrons to account for the overall charge on the ion.
In N: 2+5(= valence) = 7 electronsIn 3*O: 3*[2+6(= valence)] = 24 electronsIn negative ion charge (-1) = 1 electronIn total 32 ( = 7 + 3*8 + 1 ) of which 5 + 3*6 + 1 = 24 valence electrons in (12) covalent bonds (12 pairs).
There are 36 electrons in IF4-. Iodine has 7 valence electrons, and each fluorine atom contributes 7 valence electrons, totaling 35 valence electrons. The negative charge of -1 indicates an additional electron, bringing the total to 36 electrons.
The anion of OCl (hypochlorite ion) has 8 valence electrons. This is because oxygen contributes 6 valence electrons and chlorine contributes 7 valence electrons. The overall negative charge of the anion adds one more electron, totaling 8 valence electrons.
MgOMagnesium: 2 Valance Electrons (Charge is +2)Oxide: 6 Valance Electrons (Charge is -2)Hint: Oxide has a charge of -2 and so does Oxygen. Check the periodic table for the elements that have a -2 charge (group 16) and you will find oxygen as the first element in that group. Periods define how many energy levels the element has, just so you know. Oh and this is ionic.Hope this helps!
Sulfur, with its 6 valence electrons, will gain 2 electrons to achieve a stable octet configuration, resulting in a charge of -2.
The anion is Br+; bromine has 7 valence electrons.
