The symbol Au
What is Gold's scientific symbol?
The two main particles that make up the nucleus
Protons and neutrons
The atomic number lets you know the amount of which two atomic particles
Protons and electrons
How the periodic table was and is currently arranged
It was arranged by mass number. Now it is arranged by atomic number
Smallest known particle that does not retain the properties of an element.
Quarks
The scientists reasoning for creating the international system of symbols.
What is convenience?
The amount of quarks that make up a proton or a neutron
3
How you get the mass number
Add the number of protons and number of neutrons
Any three pieces of information the periodic table provides
Atomic number, atomic mass, element name, element symbol, state of matter, metal or not, how many valence electrons atoms have, how many shells atoms have.
Vertical column in the periodic table
Groups or families
How are chemical symbols created when the elements name is shortened?
One capital letter or a capital letter plus one or two lower case letters.
The particles that make up a majority of the atoms mass
protons and neutrons
Atoms of the same element with different numbers of neutrons
Isotopes
The number of periods in the periodic table
7
What represents the electrons in the outer energy level of an atom
Electron dot diagram
Potassium's scientific symbol
What is K?
Describe two locations of electrons
Electron cloud, shells/energy levels
The reason there is an atomic mass.
Isotopes and the changing of the amount of neutrons in an atom
The number of groups in the periodic table that tell how many valence electrons atoms of an element have
8
Weighted average mass of the mixture of isotopes
Average atomic mass
What are four ways chemical symbols are created (not including using letters from the elements name)?
Derived from Latin, named to honor scientists, places, or for properties.
The very first model of the atom. Who and what.
Proposed by Democritus. It was a positively charged sphere. No electrons.
This is what one proton or one neutron's mass is equal to
Atomic Mass Unit
The order that the dots are made in an electron dot diagram
