Question

Hi, how do I illustrate the ff?
Trends of:
1.atomic radius
2. ionization energy
3. electron negativity
4. electron affinity

Answer 1

ff?

Answer 2

following :)

Answer 3

There is alot to explain, lol

Answer 4

We dont need to define them, we just need to illustrate :D

Answer 5

Trend
For #1
- Atomic radius increases down any group because the electrons are added to a new shell. New shells are further from the nucleus, so the orbital will be larger
-Atomic radius decreases across a period because electrons are added to the (same) shell, with increasing number of protons, the positive charges got larger across a period and pulls electrons closer to the nucleus and so atomic radius decreases.

For #2,
- Amount of energy required to remove an electron in gaseous state


For #3 Electronegativity
- The tendency of an atom or a functional group to attract electrons towards itself.

Answer 6

thank you!!! :D

Answer 7

yw :)

Answer 8

how about if I were to find a chemistry news about these?

Answer 9

What do you mean chemistry news?

Answer 10

oh nvm thought we needed them for school haha thanks anyways!! :D @.Sam.
