Answer:
The valence shell has higher energy than other occupied shells
Explanation:
According to Bohr's model of the atom, he suggested that the extranuclear part consists of electrons in specific spherical orbits around the nucleus.
His model suggests that the electron can move round the nucleus in certain permissible orbits or energy levels. The ground state is the lowest energy state available to the electron. The excited state is any level higher than the ground state.
The valence electrons are in the outermost shell of an atom. These electrons are of the highest energy levels in the atom

Is this a multiple choice?
Answer:
4.34atm
Explanation:
The following data were obtained from the question:
P1 = 3.50 atm
T1 = 24°C = 24 +273 = 297K
T2 = 95°C = 368K
P2 =?
Using P1 /T1 = P2 /T2, we can obtain the new pressure as follows:
P1 /T1 = P2 /T2
3.5 / 297 = P2 / 368
Cross multiply to express in linear form:
297 x P2 = 3.5 x 368
Divide both side by the 297
P2 = (3.5 x 368) /297
P2 = 4.34atm
Therefore, the gas pressure in the container at 95°C will be 4.34atm
Using these Elements. Here would be the 4 ionic compounds.
