5, because the charge indicates the number in the valence orbital (outer shell).
6 valence electrons
how many valence electrons does family 1 have
8 valence electrons
3 valence electrons
10 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.
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
Fluorine has 7 valence electrons, however, Fluoride (F-) is an anion with a negative charge, giving it one more electron, bumping the number of valence electrons to 8.
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).
C is 4*2 H is 1*2 For a total of 10 valence electrons
13 electrons are in the third orbit of Manganese.
6 valence electrons
how many valence electrons does family 1 have
Number of valence electrons depends on number of electrons in uncharged atom(= atomic number), not on mass number. Al has atomic number = 13 and it belongs to group 13( III A) of periodic table so it's uncharged atom has 3 valence electrons. But valence electrons in ions is different. No. of valence electrons in an ion = No. of valence electrons in uncharged atom + negative charge or - positive charge1. 1. for charges only their magnitude is taken i.e. if charge is +2 or -2 then 2 is taken and put in equation.
3 valence electrons.
5 valence electrons.
