2. What is represented by the sand of time !
The sands of time is an English idiom relating the passage of time to the sand in an hourglass
The image of the sand being emptied in the hourglass creates a visual metaphor for the limited duration of human life, and for the inevitability of change in the world as a whole
3. the period in which an element is located gives us
principal quantum number (n)
4. which of the atoms and ions 1) to 4) has a different electron configuration from those of the others? 1) F- 2) Ne 3) Na+ 4) Ar
F- : [He] 2s2 2p6
Ne : [He] 2s2 2p6
Na+ : [He] 2s2 2p6
Ar : [Ne] 3s2 3p6
So, the answer must be (4) Ar -> (D)

17. A neutral hydrogen (h) atom has a single electron, while a neutral helium (he) atom has 2 electrons. which element is more reactive? why?
Penjelasan:
H is more reactive than He
The s orbital contains only 2 electrons. in the H atom, the H atom only has 1 electron and can still be filled by 1 electron, in contrast to the He atom which has 2 electrons so that the s orbital is completely filled and cannot react with another atom
