2cm x 50 = 100cm = 1m
100cm x 1000 = 100000cm

100000/2 = 50000

50000 x 5c = 250000c = $2500

What is ionic bonding?

an attractive force formed when one or more electrons is transferred from atom to another.which is held together by opposite charges formed as a result of metals losing and non-metals gainning electrons to complete their outer shell.

its like covalent bonding except it sounds cooler and these elements dont share s**t and are not part of the system.

It isnt same in anyway. As you said, elements share electrons in a covalent bond but more importantly, a covalent bond is essentially between two non metals.
