Question

A student claims that the more valence electrons an element has, the more reactive it is. Which is an accurate counterargument to this student's claim?




Alkali metals are not very reactive and have few valence electrons.

Alkaline earth metals are not reactive and have few valence electrons.

Halogens are not very reactive and have many valence electrons.

Noble gases have the maximum number of valence electrons and are unreactive.

Answer 2

D

Answer 3

thanks @mertsj can you help me with a few more questions

Answer 4

I probably won't know them, but you can post them. Someone might know.

Answer 5

@Mertsj A student carries out a chemical reaction that produces a brown powder. How should the student measure the amount of product formed?

Measure the amount of time it takes for the reaction to happen.

Remove the product from the beaker and use a scale to find its mass.

Measure the length of the powder across the bottom of the beaker.

Record the change in temperature of the beaker.

Answer 6

What do you think is meant by amount?

Answer 7

@Mertsj D?

Answer 8

What amount of money do you have. Perhaps you could find out by measuring the temperature change in your room.

Answer 10

Measuring with a scale to find the amount of product formed? That's crazy talk! :-)

Answer 11

@destinymasha that was, of course, the correct choice!

Answer 12

I liked my idea better. Measure the temperature change.

Answer 13

really?

Answer 14

Don't you mean set the money on fire and measure the temperature change? :-)

Answer 15

lol

Answer 16

Or measure the length of the skid marks in Hillary's underwear.
