A phosphorus atom and a chlorine atom are likely to form a covalent bond because both elements are nonmetals.
The name of the covalent compound CCl4 is 'Carbon tetrachloride'.
Hope this helps!
Co2 is oxygen because that what you took to ask ppl for
Density gives mass of object per volume...... Here, density is given 8.90 g/cm3 therefore, per cubic centimeter contains 8.90 g Ni. mole of Ni = mass / atomic mass = 8.90 / 58.6934 = 0.1516 mole number of atoms: mole * 6.022 * 10^23 = 0.1516 * 6.022 * 10^23 = 0.9129 * 10^23 = 0.9 * 10^23 (approx.)
