Electrons and the periodic table

Question 0

How do the properties of Electromagnetic radiation help us know what type of light is emitted?

Answer 0

Wavelengths(distance between peaks)determined the amount of frequency (peaks per second or how fast)energy(distance between nucleus and the electrons)

Question 1

Electromagnetic Radiation

Answer 1

Electro magnetic radiation is energy that travels through space and is a wave like particle

Question 2

How does light come into atoms (photo emission) ?

Answer 2

Photon is a packet of electromagnetic radiation and once it hits an electron, it bounces the electron further away from the nucleus and once it comes back it releases a certain frequency wavelength that then sends out a specific color.

Question 3

Use a periodic table or an atomic symbol to count all the subatomic particles in an atom, an ion, or isotope

Answer 3

Example would be:

Beryllium 1s^2 2s^2

Question 4

How do electrons behave (In terms of spin, energy, and movement and location)?

Answer 4

They have different levels of energy and are located in different orbitals

Question 5

What are valence electrons?

Answer 5

The electrons at the highest energy level

Question 6

what is Lower frequency?

Answer 6

Longer wave-lengths

Question 7

what is Higher frequency?

Answer 7

Shorter wave-lengths

Question 8

What is frequency?

Answer 8

Peaks per second

Question 9

The more energy an electron has….?

Answer 9

The further aways it is from the nucleus

Question 10

How many electrons can an orbital hold?

Answer 10

2 e- max

Question 11

What are the different types of orbitals? what are their shapes?

Answer 11

s,p and d orbitals. Circle, peanut and double peanut shaped.

Question 12

What is the Heisenberg Uncertainty Principle?

Answer 12

e- move every where in an unpredictable fashion, except they are in an orbital.

Question 13

What is a Photon?

Answer 13

a packet of electromagnetic radiation

Light comes from electrons

Question 14

A three-dimensional region around a nucleus where an electron may be found is called

Answer 14

Orbital

Question 15

what do the levels of energy mean?

Answer 15

The distance from the nucleus

Question 16

What is the most accurate description of how white light is changing when reflected through a prism?

Answer 16

The different wavelengths of light are being separated by a change in speed through the prism

Question 17

In a vaccum, which wave travels faster?

Answer 17

They are the same

Question 18

The more energy an atom is given…..

Answer 18

The further the electron moves in relation to the nucleus of an atom.

Question 19

Where does electromagnetic radiation , which includes visible light, come from?

Answer 19

When an atom absorbs energy,the electrons jump to a higher energy level, but can’t stay at this higher level for ever. When the electro falls back down to its ground state, a photon of electromagnetic radiation is emitted.

Question 20

Can we ever know where electrons are located?

Answer 20

No. According to the Heisenberg Uncertainty Principle, we can only know a probability of where an electron might be. We can not know for certain. Instead, they are likely in orbitals, we just don’t know where they are in the orbital.

Question 21

The drop of an electron from a high energy level to the ground state in a hydrogen atom would be most closely associated with?

Answer 21

High frequency radiation
