14:7 neutrons and 7 protons
Five: When z equals 7, the total number of electrons must also be 7, but 2 of them are in the filled inner shell of a nitrogen atom and therefore are not valence electrons.
The maximum number of electrons that can exist in 4f orbitals is 14.-pg. 110 Modern Chemistry table 2:)
Iodine has 7 valence electrons. I- contains 8 valence electron.
It can make maximum 2 covalent bonds as element of atomic number 7 has 5 valence electrons while element having 16 atomic number have 6 valence electrons.
In a neutral atom of lithium-7, the number of protons equals the number of electrons. The atomic number of lithium is 3, which is the number of protons. So a neutral atom of lithium-7 has 3 protons and 3 electrons.
The f-suborbitals begin to be filled with the lanthanoids (atomic number 57-71). Each f-suborbital can hold a maximum of 14 electrons.
No it can only hold up to 2. You have a rule for finding the maximum of electrons in every single shell. It is 2 *(shellnumber)2. Shell number 1 = 2 electrons Shell number 2 = 8 electrons Shell number 3 = 18 electrons Shell number 4 = 32 electrons Shell number 5 = 50 electrons Shell number 6 = 72 electrons Shell number 7 = 98 electrons Shell number above does for the moment not exist.
3! Electron number always equals the Proton number!
98 maximum
n=3;1=3;m1=-2;ms=+1/2 answer =0
The maximum number of valence electrons is SEVEN (7 is total number of electrons in the uncompleted highest level s- and p-orbitals: s2 and p5 = (sp)7)You'll find this mainly in group 17: the halogens, though other elements may also have 7 valences: eg. Manganese in permanganate MnO4-
