Question

general chemistry
Hi,
Good morning. I want to tell you that my score is now 70 out of 80 and I want to get the full score of 20/20 in my final test. Can you do the answer only with the symbols A, B, C, D.
Thank you, I do not want to explain only the answer because I have no time other than 50 minutes.

	b.	Transition elements
	c.	Noble gases
	d.	Inner transition elements

Answer 1

1. Rusting of iron occurs due to oxidation (b)

2. Boyle's law states that pressure and volume are inversely proportional (c)

3. Halogens have tendency to form negative ions (c)

4. Ionisation energy is minimum energy requied to remove electron from an isolated atom

5. Steel is a solid solution

6. Representative elements are are the elements between 1A and 7A
