1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^2
T/F the longer the wavelength of light, the higher its frequency
False, Lower
T/F the greater the frequency of light, the higher the energy of its photons
True
T/F The shape of a typical p orbital is similar to a four leaf clover
False, dumbbell
T/F The electron configuration of an atom gives the distribution of electrons in the ground state
True
T/F the energy of an atom in a excited state is less than its energy in the ground state
False, more
T/F Compared to a 2p orbital, a 3p orbital can contain 2 more electrons
False, contains same amount
T/F The second principle energy level of an atom can hold a total of 10 electrons
False, 8
What is the continuous Spectrum? Give an example of sources of continuous spectra.
When roygbiv colors fad into each other depending on the image and colors in pulls.
Ex: rainbow and a light dimmer
What is the photoelectric effect? how does it support the particle nature of light ?
Photoelectric effect: electrons are ejected from the surface of the metal when light shines on metal
Out of these 4 radiation options which one is not a part of the electromagnetic spectrum?
- microwave
- X-ray
- beta Ray
- infrared
Beta ray
How many electrons can a 2p orbital hold?
6
If an atom has four electrons in the ground state, how many electrons will be located in each orbital?
2 electrons in the 2 orbitals
What is an orbit?
Electrons orbiting the nucleus
What is an orbital?
Region around the nucleus where the most electrons can be found
What is a line spectrum? What are some ways it’s produced?
Line spectrum: is a series of bright lines with a frequency of light by energizing elements. One way it’s produced is by an intense flame
What is the next one number of electrons that can go into 2s?
2
