You're throwing a pizza party for 25 people and figure that each person will eat 5 slices. You call up the pizza place and learn that each pizza will cost you $ 10.00 and it will be cut into 10 slices. Every 5th pizza is free. How much is the pizza going to cost you?

5.00 I think because 5 multiplied by 5 is 25 so 5.00

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
