why does atomic size decrease across a period? Why effective nuclear charge of cation & parent atom remains the same while in anion, effective nuclear charge decreases?

Answers

Answered by harshit355

the size of atom due to effective nuclear charge
the effective nuclear remains not same as on losing electron cation become smaller as compared to parent atom

In case of anion there will be electron come in outermost orbital due to there will be lose in energy to make the electron in its orbital therforw

rubyvinod2002: What r amphoteric oxides?

harshit355: i will talk you tomorrow

harshit355: tomorrow is my test

harshit355: first make my answer brainliest please

harshit355: bye bro i will answer it tomorrow

harshit355: sorry but

harshit355: amphoteric oxides are those substances which shows both the behaviour of acids as well as base

harshit355: its nature depends whether it reacts with acid or base

harshit355: example - Aluminium oxide and Zinc oxide

harshit355: Mark this as brainliest

atomic sie decreases because attraction of electron around an atom amd proton inside a nucleous attract each other because of negative chage and positive charge.
