Question

(Calculate the following: Ion uchs cherrge > (A) Total number of electrons in CN ion. Lo elecrou (B) Number of completely filled subshells in Zinc. (Z=30) (C) The subshells in Cr having n + 1 = 4 (D) Number of unpaired electron in Sodium atom. (E) Number of electrons in s-subshell in Kr.​

Answer 1

Answer:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.
