20 Points

The smallest particle into which an element can be divided and still be the same substance. The meaning of it’s

name is “not able to be divided”.

What is an atom?

40 Points

Positively charged particle located in the nucleus of the atom.

What is a proton?

60 Points

Negatively charged particle of the atom surrounding the nucleus.

What is an electron?

80 Points

Particle located in the nucleus of the atom with no charge.

What is a neutron?

100 Points

A dense, positively charged area of the atom.

What is the nucleus?

120 Points

An atom that has the same number of protons but different numbers of

neutrons?

What is an isotope?

20 Points

What did Democritus, Dalton, Thomson, Rutherford and Bohr all have in

common?

What is they contributed to the development of the

atomic theory?

40 Points

Scientist who created the plum pudding model of the atom.

Who is Thomson?

60 Points

The plums in the plum pudding model of the atom.

What are the electrons?

80 Points

Atomic particle with the least mass.

What is an electron?

100 Points

The dense positively charged part of the atom. Most of the atom’s mass is found

here.

What is the nucleus?

120 Points

Erwin Schrodinger discovered that these are areas where the electrons are likely

to be found.

What are electron clouds?

20 Points

The number that is the same for all atoms of an element.

What is the atomic number?

40 Points

An atom that loses or gains one or more electrons and becomes a charged

particle.

What is an ion?

60 Points

The sum of the protons and neutrons in the nucleus of an atom.

What is the mass number?

80 Points

Atoms of the same element that have the same number of protons and a

different number of neutrons.

What are isotopes?

100 Points

The weighted average of the masses of all the naturally occurring isotopes of an

atom.

What is the atomic mass?

120 Points

The force that holds the protons together in the nucleus of an atom.

What is strong force?

20 Points

Something that occurs or repeats at regular intervals.

What is periodic?

40 Points

The chart that lists all the elements arranged by atomic number and set-up

in patterns that repeat

What is The Periodic Table of Elements?

60 Points

Elements that are directly on the zig-zag line or close to it and have properties of both metals and nonmetals, sometimes

they are called semiconductors.

What are metalloids?

80 Points

Group one on the periodic table with one electron in it’s outer energy level and

very reactive. (Lithium and Sodium are examples)

What are alkali metals?

100 Points

Group two on the periodic table…has two electrons in the outer energy level

and is reactive. (Beryllium and Calcium are examples)

What are alkaline-earth metals?

120 Points

Second to the last group on the periodic table…group 17…very reactive.

(Chlorine and Flourine are examples)

What are halogens?

20 Points

A vertical column on the periodic table

What is a group or family?

40 Points

Name we give a horizontal row on the periodic table

What is a period?

60 Points

Elements in group 18…unreactive, do not combine with other elements to form

compounds.

What are the Noble Gases?

80 Points

Groups 3-12 on the periodic table…also includes two special series of elements

on the bottom of the table.

What are the transition elements?

100 Points

Most are solid at room temperature and are good conductors of electricity.

What are metals?

120 Points

The physical and chemical properties of elements change…..

What is across each period?

20 Points

This is what most of the periodic table is made up of and they are located to the left of the zig-zag line on the periodic table…they are mostly

solid at room temperature and good conductors of heat and electricity.

What are metals?

40 Points

These elements are located to the right of the zig-zag line on the periodic table…they contain many gases and are poor

conductors of electricity and heat.

What are nonmetals?

60 Points

The two names of the special transition elements series located at the bottom of

the periodic table.

What are lanthanides and actinides?

80 Points

The scientist who discovered a repeating pattern to the arrangement of the

periodic table and gave it its name.

mass number of…

What is 12?

60 Points

About 20% of the air we breathe is oxygen…this element makes up the

most part of the air we breathe….almost 80%.

What is nitrogen?
