This question seems too simple to me but i was just wondering if someone could help me with it?

Question

8 a) Explain why the first ionisation energy values for the Group 1 elements become less positive as you go down the group? I have done this part it's b which is what I would like checked please.

b) Why is this called a trend?
Is it: This is called a trend because as you go down the group the positivity also goes down (devreases).

Answer 1

I looked up the word "trend" in the dictionary and came up with the following:
a general direction in which something is developing or changing."

If I might offer a suggestion to make the words flow better---
This is called a tend because it becomes easier to ionize the atom as one goes down the periodic table within a group.

Answer 2

*decreases

and ok, thank you!
