Answer: I think that trains move faster then cars! Buttt, The trains are much stronger and bigger, then cars or trucks. Even if they move slowly they can still crush something smaller then them.
Explanation: ( didnt really understand the question, but i tried)
I'm not sure what "mole" is but I am gonna assume molar so "Molar" mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
have a good day hope this helps
Gibbous refers to the moon when it is more than half full but not completely full. This results in half a circle with a smaller arc on the opposite side. This makes a weird shaped “hump” on that side which is what the humpback means.

Answer:-
[Kr] 5s1
Explanation:-
Atomic number of rubidium = 37
Atomic number of Kr = 36
So only 1 electron needs to be assigned an orbital.
Kr is also the last element of the fourth period
So the shell number for the 1 electron will be 5 since it is after Kr
Since s subshell is filled first the electron will go into 5s.
Hence the electron configuration for rubidium (Rb) in noble-gas notation is
[Kr] 5s1
