What is the definition of First Ionisation energy? The amount of energy required to remove one electron from each atom, in one mole of gaseous atoms, to form one mole of +1 ions.
What are the three factors affecting Ionisation energy? Nuclear charge, Electron shielding and Atomic Radius
How does Nuclear charge affect Ionisation Energy? As the proton number increases, the greater the nuclear charge, the greater the attraction
How does Electron Shielding affect Ionisation Energy? The more shells, the inner shells repel the outer shells, making it easier to remove electrons
How does Atomic Radius affect Ionisation energy? Further from the nucleus, means there is less attraction between the protons and electrons
Why do successive ionisation energies increase slightly? Because as electrons are removed from the atom, the atom get slightly smaller, because there is stronger attraction from the nucleus, and the electrons are pulled in?

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.
