CHEM-120 week 2 quiz and answers
verified to pass 2025
Flame test - correct answer ✔different elements give different colors when
placed in a flame
Line spectra - correct answer ✔When light from an element passes through
a prism, it produces a line spectrum.
Quantum - correct answer ✔A tiny unit of energy produced or absorbed
when an electron makes a transition from one energy level to another.
Ground state - correct answer ✔When electrons are in the lowest energy
state, they are said to be here.
Excited state - correct answer ✔When energy from a flame or other source is
absorbed by the electrons, they are promoted to a higher energy state.
Photon of energy - correct answer ✔This is emitted when an electron in an
excited state returns to a lower state. May be observed as light.
Shells - correct answer ✔Energy states or levels are sometimes known as
this _____.
The higher the energy level .... - correct answer ✔the further from the
nucleus
Quantum Model - correct answer ✔of the atom is a probability - based
model. It is composed of principal energy levels, sublevels, and orbitals.
, Principal energy levels (shells) - correct answer ✔roughly correlate to the
distance that an electron is from an atoms nucleus
Sublevels (subshells) - correct answer ✔each principal energy level (n) is
divided into n sublevels. Each sublevel has one or more orbitals.
Orbitals - correct answer ✔are regions in space that represent a high
probability of locating an electron.
Electron configuration - correct answer ✔allow us to represent the
arrangement of the electrons in an atom
Octet Rule - correct answer ✔atoms gain, lose, or share electrons in order to
have 8 valence electrons
Duet Rule - correct answer ✔atoms gain, lose, or share electrons in order to
have 2 valence electrons *** only true for hydrogen and helium***
Many nonmetallic elements react by - correct answer ✔sharing electrons
rather than gaining or losing
Periods - correct answer ✔Horizontal rows in the periodic table. These
elements demonstrate a range of properties from metallic (on the left) to
nonmetallic (on the right).
Max # of electrons in S orbital - correct answer ✔2
Max # of electrons in P orbital - correct answer ✔6
