HELP ME PLEASE I BEG Can someone explain what the heII lattiCE STRUCTURES ARE. WHY IS IT THAT NaCl HAS 27 ATOMS IN ITS STRUCTURE WHEN THE BALANCED MOLECULE HAS 2 ATOMS?? WHAT HAPPENS TO THE LAST ONE??? WHAT IS A CELL UNIT?? I THOUGHT CELLS WERE A BIO THING? PLEASE IM DESPERATE THIS IS ALL THE POINTS I HAD

please to all the kind souls out there, i just wanna pass chem ;-;

A lattice structure is a space-filling unit cell that can be tessellated along any axis with no gaps between cells. These structures are an emerging solution to weight, energy and advanced manufacturing time reduction

id k the second and third one

A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal. A crystal can be thought of as the same unit cell repeated over and over in three dimensions

hope it helps this is all i can do

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d
