Answer:

True

Explanation:

A metal , has 1 electron on the last level, so it can become (A^+1)

C, non-metal, has 7 electrons on the last level, so it can become (C^-1)

Jobisdone [24]

Answer:

Explanation:

Given that:

The argon atoms are excited into an excited state before emitting the 488.0 nm laser.

the energy of the first ionization energy of argon is 1520 kJ mol-1.

SInce 1 eV = 96.49 kJ/mol

Therefore, the energy of the first ionization energy of argon in eV is = ( 1520/ 96.49) eV

= 15.75 eV

To find where the energy level of the excited state lies below the vacuum energy level, let's first determine, the energy liberated by using planck expression.

$E = \dfrac{hc}{\lambda}$

$E = \dfrac{6.6 \times 10^{-34} \times 3 \times 10^8}{488 \times 10^{-9}}$

$E = \dfrac{1.98 \times 10^{-25}}{488 \times 10^{-9}}$

$E =4.057 \times 10^{-19} \ J$

Converting Joules (J) to eV ; we get,

$E =\dfrac{4.057 \times 10^{-19}}{1.6 \times 10^{-19}}$

E = 2.53 eV

The energy levels of the first exited state = -13.223 eV
