Question 6

What is the smallest part of an ionic compound?

Answer 6

formula unit (f.u.)

Question 7

What is the smallest part of a molecular substance?

Answer 7

molecule

Question 8

How to name an ionic compound?

Answer 8

univalent (Na,K) don’t need roman numeral

multivalent needs, uncrisscross to find charge

Question 9

How to name a molecular compound?

Answer 9

use prefix method, mono isn’t used for first element, no prefix if H at front (like ionic)

Question 10

How to write formula of ionic compound?

Answer 10

crisscross method

Question 11

How to write formula of molecular compound?

Answer 11

prefixes (don’t reduce to lowest terms)

Answer 12

Electrolyte- produce mobile ions in solution which can conduct, high melt points

Question 13

What are the properties of Molecular substances?

Answer 13

Non-electrolytes (except acids), soft, low melt point
