General Chemistry
This is the study of matter and how it changes.
What is chemistry?
These particles are found in the nucleus of an atom.
What are protons and neutrons?
The lowest energy state of a particle
What is ground state?
In any chemical or physical process, the total mass of everything involved must remain the same.
What is the Law of Mass Conservation?
This is a measure of how much matter is in an object
What is mass?
List the visible light in order from longest to shortest wavelength.
What is red, orange, yellow, green, blue, indigo, violet?
This is two or more atoms of the same element that have different numbers of neutrons.
What is an isotope?
What is the chemical symbol, atomic number and mass?
This states that electrons fill orbitals starting with the lowest energy and then filling the higher energy orbitals as necessary.
What is the Aufbau Principle?
What is Volume?
Elements in the same ________ or _________ of the Periodic Table have similar chemistry.
___, ___, and ___ are three main electron orbitals.
What are s, p and d?
Ground state electron configuration for silicone
What is 1s22s22p63s23p2
When two elements combine to form different compounds, a fixed amount of one element will combine with the other element so that the ratio of the masses of the other element is a small whole number.
What is the Law of Multiple Proportions?
There is always uncertainty in the last number of this.
What is significant figure?
The Concept that light as well as subatomic particles have properties of both particles and waves
What is wave-particle duality?
These increase the mass of an atom.
What is a neutron?
The chemical symbol with mass number of an element with 19 protons and 21 neutrons.
40 K
A given compound will always have the same proportion of elements by mass.
What is the Law of Definite Proportions?
This is based on significant figures, while this depends on how close the measurement is to being correct.
What is precision and accuracy?
_________ ____________ happens when two waves add together and create a bigger wave. _________ __________ happens when crests and troughs overlap and cancel each other out.
What is constructive interference and destructive interference?
A _____ will change their electron configuration by losing electrons, while ______ will gain electrons.
What are cations and anions?
Abbreviated ground state electron configuration for bromine.
What is [Ar]4s23d104p5
This describes electrons in an atom as wave functions, not fixed orbits, exhibiting wave particle duality, and predicts the probability of finding an electron in an orbital.
What is the Quantum Mechanical Model?
How many significant figures are in 708,000 in
What is 3?
