covalent compounds:

1. the 2 elements in an covalent compound are a and a
2. what do the prefixes in the name of a covalent compound tell a scientist?

how many

1. which prefix is not always used when naming a covalent compound?
2. list the prefixes meaning 1-10 used for naming covalent compounds below:

#	prefix	#	prefix
1		6	hexa
2	di	7	hepta
3	tri	8	octa
4	tetra	9	nona
5	penta	10	deca

determine the name or the formula for the following covalent compounds based on the information provide:

1. $so_2$ :
2. phosphorus pentachloride:
3. $co$ :
4. carbon tetrachloride:
5. $brf_5$ :

Explanation:

Step1: Name SO₂

1 S (no prefix, "mono-" omitted for first element) + 2 O ("di-") → sulfur dioxide

Step2: Formula for phosphorus pentachloride

1 P + 5 Cl ("penta-") → PCl₅

Step3: Name CO

1 C (no prefix) + 1 O ("mono-") → carbon monoxide

Step4: Formula for carbon tetrachloride

1 C + 4 Cl ("tetra-") → CCl₄

Step5: Name BrF₅

1 Br (no prefix) + 5 F ("penta-") → bromine pentafluoride

Answer:

1. sulfur dioxide
2. PCl₅
3. carbon monoxide
4. CCl₄
5. bromine pentafluoride
