Atoms that gains one or more electrons during a chemical reaction become___ charged ions or fill the gap A:positively, anions. B: negatively, cations
Plz answer I be rlly thankful for your help

option B

Explanation:

In Any chemical reaction when an atom gain electrons it become negatively charged ion or cation. For Example oxygen gains 2 electrons and become O-2 ion. And if an atom accept electrons it become positively charged ions for example when magnesium gain 2 electrons it become Mg+2 charged ion.

Atom with negative charge have excess electrons and can lose its electrons while atom with positive charge are deficient in electron so can accept electrons.

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity
