Answer:  None of the options

Explanation: 2, 8, 4 represents a total of 14  electrons.  

The 2:   1s^2

The 8:  2s^2 2p^6

The 4:   3s^2 3p^2

Assuming a neutral atom, 14 electrons represnt element #14, Silicon.  The electron configuration matches that of silicon,  But silicon is in group  14, which is not in the options.  It is a metalloid, so if there is another grouping system, use the nuimber assigned to the metalloids.  But the word "Group"normally refers to the column number, 14 for silicon.  And I've never heard of Group 0.

Which orbital would the electron of a ground state hydrogen atom occupy? 1s 1p 2p none of the above 0s?
noname [10]
From the periodic table, we can see that:
At ground state, the hydrogen atom has one electron
Based on the electronic configuration, at ground state this electron should be occupying the orbital (1s)

Since (1s) is not one of the choices, therefore, the answer is "none of the above"

The reduced vapor pressure at high altitudes causes a liquid to boil at a temperature.
irinina [24]
<span>At higher altitudes (and thus lower atmospheric pressures), water boils at a lower temperature. This is because the lack of vapor pressure at that altitude doesn't constrain the speed of the molecules with barometric pressure. Therefore, the water begins boiling at a lower temperature. This is often a disadvantage because even if the water is boiling, it won't be hot enough for meals (which is why heat and temperature are distinct). That's why we have pressure cookers, which manage to keep a stable boiling point.
