Answer:
2.5 x 10⁻⁹ m
Explanation:
E = Energy of photon = 500 eV = 500 x 1.6 x 10⁻¹⁹ J
c = speed of photon = 3 x 10⁸ m/s
λ = wavelength of photon = ?
Energy of photon is given as
inserting the values
λ = 2.5 x 10⁻⁹ m
Explanation:
Atoms of some elements shows no desire to form bonds or combine with themselves or other kinds of atom because their outer energy levels are completely filled.
Helium has a duplet configuration whereas other atoms of the noble gases have an octet configuration.
- The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
- The various interatomic bonds form in a bid of the atom to be isoelectronic in the outer energy level with the noble gases.
- This leads to loss, gain or sharing of electrons between atoms.
