The number of electrons will be 118.
The group number tells you the number of valence electrons present.
A neutral barium atom has 56 electrons.
52
There are three lone pairs present in chlorine atom
There are 50 electrons in a sulfate ion. 16 in the sulfur 8 in each of the 4 oxygen 2 for the negative charge so the total electrons are 50
That depends on the element you are considering. For a neutral atom, the number of electrons = number of protons = atomic number
The group number tells you the number of valence electrons present.
