Answer:Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge.
Explanation:
Fe: 2 x 55.845 = 111.69
O: 3 x 15.9994= 47.9982
111.69 + 47.9982 = 159.69 g/mol

Explanation:
Let 
be the volume of the given material.
Let 
be the mass of the material.
Let 
be the density of the material.
Density of a material is defined as the ratio of its mass to its volume.
Given,
So,
<span>It is said
that the carbon atom is a tetra valence which means, it contains 4
covalent bonds that can be bonded with other atoms. Therefore, it needs 4
hydrogen atoms to bind into 1 carbon atom. Carbon Atom contains a total of
6 electrons that occupies the 2 shells which is the K (have 2 electrons)
and L (have 4 electrons) shells. The
outermost shell of carbon atoms that contains 4 electrons is called as
valence shell. In order to complete its octet, carbon Atom needs other
atoms to share their valence electrons.</span>
