How many protons does v have?

Answer 1

Vanadium has atomic number 23 which means it has 23 protons in the nucleus.

Vanadium has Atomic Mass 51 which means it has (51 -23) 28 neutorons in the nucleus.

Neutral Vanadium has exactly the same number of electrons as there are protons in the nucleus, so neutral Vanadium has 23 electrons.

An 3+ ion of Vanadium has 3 less electrons, so it has 20 electrons (and it still has 23 protons in the nucleus, so the charge is the difference, i.e. +23-20 = +3).

So Vanadium 3+ has 20 electrons and 23 protons (The neutrons stay the same at 28 neutrons).

Answer 2

V stands for element Vanadium. It occupies the 23 rd block allotted for it. So it has to have 23 protons. The number of protons decides the name of element. Hence the number of protons is known as atomic number Z. So every element would have only one atomic number. If atomic number is known then we can identify the element and if element is given then we get the atomic number. So if 47 is the atomic number then it has to be Ag, ie silver. Gold ie Auric has 79 as atomic number. Copper ie Cu has 29 as atomic number. These three are known as coinage metals. All these three lie in the same group.

Fe, Co, Ni just for the memorizing purpose it is pronounced as feconi just rhyming as Marconi. These elements have atomic numbers in successive order. They are 26,27 and 28. So these are neighbours.

Answer 3

Vanadium metal contains 23 protons. V-3 ion contains 23 protons too.

Answer 4

23

Answer 5

20
