What happens to a electron when it jumps ahead to a higher energy level

leaves on from the inner principal energy level partly empty

when the excited electrons go back to lower energy levels they give off energy which produces a spectrum

of colors or bright line spectrum

Each atom has its own distinct pattern of

emission lines (bright light spectrum)

the light given off by a neon or fluorescent light is caused by

exited electrons returning to lower energy levels

The characteristic spectral lines of elements are caused when (electrons in an exited atom move from ) (exited to ground state)

higher to lower levels releasing energy

how an atom in the ground state becomes exited

the atom absorbs energy and one or more electrons move to a higher electrons shell

Question	Answer
The charge of the nucleus is equal to	the atomic number
the first shell of the Bohr model is the closest to the	nucleus
electrons in the first energy level have the	lowest energy
electrons are found in an	orbitals
orbital region where an___can most likely be found	electron
The first principle of the electron shell has how many electrons	2
The second principle of the electron shell has how many electrons	8
The third principle of the electron shell has how many electrons	18
The fourth principle of the electron shell has how many electrons	32
When the electrons occupy the lowest available orbitals the atom is said to be in the	ground state
When electrons are subjected to stimuli such as heat light or electricity an electron may absorb energy and temporarily move to a higher energy level this is called	excited state
an excited state electron quickly returns to a lower available level, what does it emit	the same amount of energy
What happens to a electron when it jumps ahead to a higher energy level	leaves on from the inner principal energy level partly empty
when the excited electrons go back to lower energy levels they give off energy which produces a spectrum	of colors or bright line spectrum
Each atom has its own distinct pattern of	emission lines (bright light spectrum)
the light given off by a neon or fluorescent light is caused by	exited electrons returning to lower energy levels
the atomic number of an atom is always equal to the total number of	protons in the nucleus
how do you find the mass number	P+N (protons plus neutrons)
which quantity can vary among atoms of the same element	mass number
isotopes of the same element must have the same	atomic number
the atomic mass of an element is defined as the weighted average mass of that element’s	naturally occurring isotopes
The characteristic spectral lines of elements are caused when (electrons in an exited atom move from ) (exited to ground state)	higher to lower levels releasing energy
as an atom in the exited sate returns to the ground state the energy of the atom	Decrease
When compared with the energy of an electron in the first shell of a carbon atom the energy of an electron in the second shell of a carbon atom is	greater
how an atom in the ground state becomes exited	the atom absorbs energy and one or more electrons move to a higher electrons shell
