Electron shells

what factors effect ionisation energy? Atomic Radius, Nuclear charge and Electron sheilding
What is atomic radius? what effect does it have on ionisation energy required? atomic radius is the distance of the electron from the nucleus. The greater the atomic radius the less attraction experienced by the outer electrons (less ionisation energy needed)
What is nuclear charge? what effect does it have on ionisation energy required? nuclear charge is the charge of the nucleus (because of the protons. The greater the charge the more attraction felt by the electrons (more ionisation energy needed)
what is Electron sheilding? what effect does it have on ionisation energy required? inner shells of electrons repel outer shells? the more electron shells the more electron shielding there is and the less ionisation energy is required to remove electrons
you are given a table of energy required for 8 ionisation numbers for an atom how do you tell which group it is in? look for a large "jump" in energy required the ionisation number should tell you when it moves to a new shell (showing which group it's in) if there is no "jump" it will likely be in group 0
What is first ionisation energy the amount energy required to turn 1 mole of a gaseous atoms to turn it into a +1 ion

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
