Plzzzz Answer !!!!!​

Answer 1

1. Y.will have more mentally character as it is to the left of X.. mettaloc character decrease as we move across a period from left to right
2. X will have larger atomic size because atomic size increases as we move across a period
3. X will have affinity for electrons as it is towards the side of non metals
