Electron configuration

Question 1

Charge on an electron

Answer 1

negative

Question 2

Charge on a nucleus

Answer 2

positive

Question 3

How do systems behave

Answer 3

Systems behave in such a way as to reduce stored energy

Question 4

Behaviour of electrons (electrostatic forces)

Answer 4

Like charges repel, electrons repel each other

Unlike charges attract, electrons are attracted towards nuclei

Question 5

Behaviour of electrons (magnetic forces)

Answer 5

If you try to push 2 electrons together, they tend to align anti-parallel

Question 6

Behaviour of electrons (electron stacking)

Answer 6

No 2 electrons can occupy the same state

Question 7

Behaviour of electrons (electrons as quantum objects)

Question 8

Behaviour of electrons (ground state)

Answer 8

The lowest energy state

Question 9

How many electrons can be in one orbital

Answer 9

0, 1 or 2

Question 10

What is electron shielding

Answer 10

The repulsive force exerted by inner shell electrons on outer shell electrons, pushing them away from the nucleus
