Answer is: They orbit the central nucleus in discrete paths.
According to the Bohr model of the atom:
1. Electrons orbit the nucleus in orbits that have a set size and energy.
2. Energy levels of electrons are discrete (certain discrete values of energy).
3. Electrons can jump from one energy level to another, absorbing or emitting electromagnetic radiation with a frequency ν (energy difference of the levels).
Answer: 71.43g
Explanation: The RMM of NaHCO3 is
23+1+12+16(3)=84.
There is one carbon in NaHCO3 thus there are 1×12g of C in NaHCO3.
Thus
85gNaHCO3-----12g C
500gNaHCO3---- xgram
(500×12)÷84= 71.43
