Explanation:
It is known that for a body centered cubic unit cell there are 2 atoms per unit cell.
This means that volume occupied by 2 atoms is equal to volume of the unit cell.
So, according to the volume density
2 atoms =
=
Formula for volume of a cube is . Therefore,
Volume of the cube =
As lattice constant (a) =
=
Therefore, the value of lattice constant is .
And, for bcc unit cell the value of radius is as follows.
r =
Hence, effective radius of the atom is calculated as follows.
r =
=
=
Hence, the value of effective radius of the atom is .
Some metals are copper,zinc,lead, or nickel I hope this answers your question
The total charge of a compound must be zero. So the Y ion has charge of -2. Then the charge of X ion+(-2)*2=0. So the charge of X ion is +4.

To make this equation right, coefficients must be added in front of molecules, so number of atoms in right and left are equal.
2O₂ + CH₄ = CO₂ + 2H₂O
How, you have 4 atoms of oxygen,1 atom of carbon and 4 atoms of hydrogen on both side of reaction.
