How many electrons are in the highest energy level of oxygen?
Oxygen has eight electrons. The first two electrons will go in the n=1 level. Two is the maximum number of electrons for the level so the other electrons will have to go in a higher energy level. The n=2 level can hold up to eight electrons so the remaining six electrons will go in the n=2 level.
Which valence electrons have the most energy?
The outermost orbital shell of an atom is called its valence shell, and the electrons in the valence shell are valence electrons. Valence electrons are the highest energy electrons in an atom and are therefore the most reactive.
How many valence electrons does oxygen O have on its highest energy level?
six valence electrons
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
What is the highest valency of oxygen?
Option (a) – Chlorine has the highest valency with respect to oxygen.
What is the energy level of oxygen?
Energy Levels of Neutral Oxygen ( O I )
| J | Level(cm-1) | Ref. |
|---|---|---|
| 0 | 33792.583 | MG93 |
| 2 | 73768.200 | MG93 |
| 1 | 76794.978 | MG93 |
| 1 | 86625.757 | MG93 |
Why do valence electrons have the highest energy?
So a large amount of energy is required to liberate an electron from an inner most shell rather than an electron from the outermost shell. This is why we say that the electron in the outermost shell has a higher (potential) energy than the inner most shells.
What is the highest valency?
As it belongs to the VI Periodic Table group, Sulphur has six valence electrons. It thus has maximum valency.
Which has higher valency oxygen or sulphur?
Valency of oxygen is generally two whereas Sulphur shows valency of two, four and six.
Which electron has the highest energy level?
Number of electrons per sublevel
| Energy Level | Sublevels | Maximum Number of Electrons per Energy Level |
|---|---|---|
| 1 | s | 2 |
| 2 | s | 8 |
| p | ||
| 3 | s | 18 |
Which electrons has the highest energy level?
Which is the highest energy level?
Which element has higher valency K or O?
(ii) Element k has a higher valency as valency of k = 3 and the valency of o = 1.
Which is more reactive oxygen or sulphur?
oxygen is only more reactive than sulphur because due to small atomic size oxygen atom has high tendency to attract the electrons ( more electronegative )….
Which is the highest energy?
Record-shattering gamma rays from exploded star detected by observatory in Tibet in China. A collaboration of Chinese and Japanese astrophysicists has reported the highest energy photons ever seen: gamma rays with energies up to 450 trillion electron volts (TeV).
