Electronic configura

Electronic configuration

QuestionAnswer
What is an electronic configuration? The arrangement of electrons in an atom is called its electronic configuration.
How many electrons can each energy level hold Energy level 1 = 2 electrons max Energy level 2 = 8 electrons max Energy level 3 = 8 electrons max Energy level 4 = 18 electrons max
What are positive ions called Cations
What are negative ions called Anion
Why is a cation formed the ion gets rid of electrons
Why is a anion formed the ion gains electrons
What is a continuous spectra? A continuous spectrum is the band of colours produced when light is separated into its components Since different colours of light have different wavelengths, they have different degrees of refraction causing the colours to be seen separately
What is a line emission spectra? A line emission spectrum occurs when a tube of hydrogen gas (or other element) that has an electric current passed through it is separated into its components Each element has its own unique line spectrum studied using spectrometer.
What is an Energy Level? The fixed energy value that an electron in an atom may have
What is the Ground State? It is the state in which the electrons occupy the lowest available energy level
What is the Excited State? It is the state in which the electrons occupy the higher energy level than those available in the ground state.
What is a Photon? Photon energy is the energy of a single photon. It is proportional to the frequency of a photon
What is the frequency of a photon? The frequency of a photon is defined as how many waves pass a certain point per second.
How do line emission spectra arise? Electron occupies the ground state. Energy is absorbed as heat or electricity causes the electron to jump to a higher energy level. It is now in the excited state but its is unstable. It drops back to a lower energy level emitting a photon of light.
How do line emission spectra arise? Energy difference between levels gives energy of photon which is calculated by Em – En = hf .

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.

To see how well you know the information, try the Quiz or Test activity.
