Nails are made up of iron not of phosphorus and barium.  

As both phosphorous and barium are relatively weaker than iron ,phosphorus breaks easily and barium is also fairly weak. Iron nails are already also not that strong, but their weight and strength are sufficient.  

So the nails are made up of iron.

Calculate the molecular formula of a compound with the empirical formula C5H11 and a molar mass of 142.32 grams/mole
MA_775_DIABLO [31]
Relative formula mass C₅H₁₁ = 71

Now divide the molar mass by the RFM = 142.32 / 71 = 2

Now C₍₅ₓ₂₎H₍₁₁ₓ₂) = C₁₀H₂₂

HELP! An atom of vanadium
Zigmanuir [339]

An atom of vanadium (V)  has 23 electrons.

Given :

A vanadium (V) atom with 23 protons and has a net charge of 0.

To find:

The number of electrons in a vanadium atom

Solution:

Number of protons in vanadium atom = 23

The 0 net charge on the atom indicates that the atom has an equal number of protons and electrons which makes it a neutral atom.

Number of electrons in vanadium atom = Number of protons in vanadium atom = 23

An atom of vanadium (V)  has 23 electrons.
