Is also called a family

What are groups?

Rows across the periodic table

What are periods?

Most reactive group of metals

What are alkali metals?

There are 18 of them and they have common properties within

What are groups?

The only classification that has only one element in it

What is Carbon?

The positively charged particle in the nucleus of an atom

What is the proton?

The uncharged particle in the nucleus of an atom

What is the Neutron?

Orbits the nucleus of an atom in a cloud

What is an electron?

What the majority of an atom is

What is empty space?

The atomic particle with the smallest mass

What is the electron?

The original inventor of the periodic table

Who is Mendeleev?

He shot alpha particles at gold to disprove the plum pudding model

Who is Rutherford?

A student of Rutherford who created the planetary model of the atom still used today

Who is Dalton?

“Science” didn’t exist in early B.C. so it was considered this

What is philosophy?

Mendeleev’s periodic table was arranged by this; unlike the modern periodic table

What is Atom Mass?

Number that must be rounded before using to calculate neutrons

What is Atomic Mass?

The number of neutron in Aluminum; which has an atomic mass of 26 The number of neutron in Aluminum; which has an atomic mass of 26.982 and a Atomic Number of 13

What is 14?

The Atomic Mass of Helium; which as 2 neutrons, 2 electrons, and 2 protons

What is 4?

The reason Atomic Masses are usually decimals instead of whole numbers

What is the average of all naturally existing isotopes?

The element with 1 proton in the nucleus

What is Hydrogen?

A property of metals that means to be workable with a hammer

What is malleable?

A liquid metal

What is Mercury?

Has properties of both metals and nonmetals

What are metaloids?

An element with electrical conductivity but is also brittle; found in pencil lead

What is Carbon?

The group of nonmetals that are not reactive

What are Noble Gases?
