No. It must reach the minimum threshold energy. Since its only half, there isn't enough energy for the electron to jump to the 2s energy level.
Side note: An electron can only jump between energy level if the minimum energy is met. If the energy of the photon does not meet this energy level and is below, the electron will not jump to the new level.

Answer:
The new volume is 2415 mL
Explanation:
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases.
Boyle's law says that the volume occupied by a given gas mass at constant temperature is inversely proportional to the pressure and is expressed mathematically as:
P * V = k
Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:

Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the gas pressure increases. And when the temperature is decreased, the gas pressure decreases. This can be expressed mathematically in the following way:

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

Having two different states, an initial state and an final state, it is true:

In this case:
- P1= 0.9 atm
- V1=4,600 mL= 4.6 L (being 1 L=1,000 mL)
- T1= 195 °C= 468 °K (being 0°C=273°K)
The final state 2 is in STP conditions:
- P2= 1 atm
- V2= ?
- T2= 0°C= 273 °K
Replacing:

Solving:

V2= 2.415 L =2,415 mL
<u><em>The new volume is 2415 mL</em></u>
