Wave speed = frequency x wavelength
= 100 x 0.3
= 30 m/s.
Hope this helps!
Their atomic number increases
Hydrogen is the only atom that does not have neutron electrons in the first energy level/shell.
Answer: No charge (0)
Explanation:
The atom has a proton of 22 and electron number of 19. This means the element has lost 3 electrons. Therefore, the net charge is +3.
So, if this atom gains 3 more electrons, the net charge would be zero (neutral).
The total number of electron would now be 22 which is the same as the proton number.
This implies the atom is now in an unreacted state or ground state.
