Periodic Table
100
The positively charged part of the atom
What is the proton?
100
A elemental metal that has the chemical symbol Cu
What is copper?
100

For the isotopic notation below, which is the proton number?

7

100

The electrons that in the highest energy level of the atom and held most loosely

What are valence electrons?

100
The number of protons in an atom
What is atomic number?
200
The part of the atom that has no charge
What is the neutron?
200
Several elements that lie along a zigzag line between metals and nonmetals. Depending on conditions these elements behave as either metals or non metals.
What is metalloid?
200

What are variances of the same element, meaning the atoms have the same number of protons but different number of neutrons, producing different forms of the same element

isotope

200

What are columns called on the periodic table?

group

200
The average mass of the isotopes of an element found in nature
What is atomic mass?
300
The negatively charged part of the atom
What is the electron?
300
These elements are located in Group 18 and are non-reactive
What is noble gas?
300

What is the relative distance and position an electron holds from the nucleus, least densely populated area of the atom

orbital

300

What are rows called on the periodic table?

period

300

How are groups arranged?

by valence electrons

400
This is created when we have both the protons and the neutrons
What is the nucleus?
400
These elements are located in Group 17 and gain just one more electron in order to gain stability
What is halogen?
400

The average mass of an element expressed in Atomic Mass Units and is approximately equal to the number of protons and neutrons in an atom; often referred to as the mass number

What is atomic mass?

400

What happens to electrons when you move across the periodic table?

The number of valence electrons increases, but the number of shells remains constant

400
A representation of an element usually consisting of one or two letters.
What is the chemical symbol?
500
The location of the electrons in the atom
What is the orbit?
500
These elements are the most reactive group of atoms and are found in Group 1
What are the alkali metals?
500

Atoms are most stable when their outermost shell has 8 electrons

What is the octet rule? 

500
These elements make good conductors of electricity.
What is a metal?
500
The horizontal rows that the periodic table is organized in
What is a period?
