How many protons and neutrons are there in B 5’11 respectively?
So boron-11 has five protons the same as boron-10. Then the mass number is total protons plus neutrons. For boron-11 this total is 11, and five of the particles are protons, thus 11−5=6 neutrons.
How many neutrons are in mass number 11 and atomic number 5?
Therefore, proton is 5. Atomic mass (A) is 11 and atomic number (Z) is 5. Neutrons = 6.

Where is V found?
Vanadium is mined mostly in South Africa, north-western China, and eastern Russia. In 2013 these three countries mined more than 97% of the 79,000 tonnes of produced vanadium. Vanadium is also present in bauxite and in deposits of crude oil, coal, oil shale, and tar sands.

What is the atomic number of an element?
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
What is the atomic mass of an element measured in?
Atomic Masses. The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D).
What is the unity for the atomic mass of elements?
The unity for atomic mass is gram per mol. Please note that the elements do not show their natural relation towards each other as in the Periodic system. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals.
