How many electrons does phosphrous have to gain or loose to have 8 valence?
Phosphorus, with 5 valence electrons, needs to gain 3 electrons to have a full set of 8 valence electrons. This would allow it to achieve a stable octet configuration, resembling the noble gas configuration of argon.
What is the r elationship of number of valence electrons of elements to their group in the periodic table?
Valence electrons are in the outer shell of the atom. The first column (group 1)has a +1 valence, which means that it has an extra electron it can 'lose' when bonding with other atoms. The 2nd column (group 2) has +2. The same goes for groups 3. Group 4 can gain 4 and lose 4. Group 5 can 'gain' 3 electrons, group 6 can gain 2 electrons etc.
How many electrons must phosphorus p gain or lose to have 8 valence electrons?
Phosphorus wants to gain three electrons to have 8 valence electrons.
What is the rule?
atoms either loose or gain a maximum of 2 valence electrons like hydrogen
What group of elements gain two valence electrons when the atom form ionic bond?
Group 16 or the chalcogens.
How many valence electrons must sulfur gain or lose to get 8 valence electrons?
Sulfur has 6 valence electrons. To achieve 8 valence electrons, sulfur must gain 2 electrons to fill its outer shell and satisfy the octet rule.
How many electrons phosphorus must gain or lose to have 8 valence electrons?
Phosphorus wants to gain three electrons to have 8 valence electrons.
Does fluorine gain or loose electrons?
Fluorine gains electrons to achieve a stable electron configuration. It has seven valence electrons and tends to gain one more electron to complete its outer shell and attain a full octet.
How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
How many valance electrons are in an atom that has 15 electrons?
Group #15 has 5 valence electrons
How will atoms with 5 valence electrons achieve a full set of valence electrons?
They will gain 3 electrons from something with 3 valence electrons.
Does group 13 elements lose or gain valence electrons?
Group 13 elements tend to lose three valence electrons to achieve a full outer shell configuration. They typically form 3+ ions by losing these three electrons.
