In Period 3 of the Periodic Table, element B is placed to the left to element A.​

A. Element B would have (lower/higher/same) metallic character than A.​

B. Element A would probably have (lesser/higher/same) valence electrons than B ​

C. Element A would have (greater/smaller/same) atomic size than B.​

1. A. Higher, B. Same C. Smaller​
2. A. Higher, B. Higher C. Same​
3. A. Same, B. Same C. Smaller​
4. A. Lower, B. Same C. Greater​
