Question

For the main group elements,in general, upon going from left to right across a period of the periodic table, the ionization energy__，theatomicsize，__ and the metallic character__

Answer 1

ADS For the main group elements in genesal upon going from left to right across a period of the periodic table, the lonization energy increases the atomic size decreases and the metalic character decreases Explanation: In periodic table,

Explanation: In periodic table, In group , top to bottom lonization energy gradually decreases In period, left to right losstation energy gradually increases due to nuclear charge increases * Atomic Size Col radius & The atomic radius increases from top to bottom in the groups due to increated in the number of shells * The atomic radius decreases from left to right in a periods due to increases in nuchel charge and electrons close to the nucleus

now & metalic characted In groups ie top to bottom, metalic nature increases and - metallic nature decreases In periodo je left to right, metalic nature decrease non metalic nature increases
