Phosphorus has 10 more electrons.
A neutral atom of phosphorus has 15 electrons, 3 in the outer 3p shell There are 5 electrons in a neutral atom of boron, 1 in the outer 2p shell.
3 more than it already has
18. Phosphorus posses 15 electrons and 15 protons, respectively its charge is 0.By accepting 3 more electrons, with their negative charge the total charge of the atom would decrease by 3.So the total charge would be -3 and the total number of electrons would be 18.
A metal in the alkali metal family has one valence electron where as a metal in boron family has three valence electrons. It is easy to remove one valence electrons than three. So alkali metals will be more reactive.
I think lithium should be more reactive as it has only 1 valance electron wheres Boron has 3 valance electrons. The electro positivity(tendency to lose electrons) of Lithium is greater then Boron, therefore more reactive.
Nitrogen and phosphorus have the same number of valence electrons (five) and will have similar properties.
phosphorus
3 more than it already has
The atomic number of phosphorus is 15.its electronic configuration is 2,8,5.outermost shell has 5 electrons. it can accommodate 3 more electrons to complete its octet.so its valency is 3. and it has 5 electrons on its valence shell.
Calcium
Lewis Acid are able to accept electrons. Boron in Boron Trifluoride only contains 6 electrons, thus making it able to receive 2 more electrons to complete it's octet. Also, Boron is an exception that it is stable with a sixtet, which makes it BF3 a neutral molecule.
There are 15 electrons in a phosphorus atom, but only if it is neutral. The element phosphorus, a nonmetal, is not found free in nature because it is reactive and has loaned out two or more electrons. It has a number of oxidation states ranging through 2, 3, 4 and 5 (and also a -3). The number electrons in a given phosphorus atom will vary depending on its chemical circumstances.
It can only make three bonds. Boron has three valence electrons and therefore cannot form more than three bonds with no lone pairs.
fewer
Phosphorus with 3 more electrons than protons.
Aluminium has three valence electrons and phosphorous has five, hence the latter has more.
If phosphorus forms a monatomic ion, it gains electrons and form a phosphide ion. More commonly, however, phosphorus forms a polyatomic anion including one or more oxygen atoms. The bonds within these polyatomic anions are covalent, but phosphorus is considered to have a positive oxidation number in such anions, and positive oxidation number corresponds to losing electrons.
18. Phosphorus posses 15 electrons and 15 protons, respectively its charge is 0.By accepting 3 more electrons, with their negative charge the total charge of the atom would decrease by 3.So the total charge would be -3 and the total number of electrons would be 18.
