A neutron walks into a shop and says, “I’d like a coke."

The shopkeeper serves up the coke."How much will that be?" asks the neutron.

The shopkeeper replies, "For you? No charge."

This particular element accounts for about 90% of

the total mass of the universe.

Hydrogen

Who was the British scientist who proposed the idea that each element

is made up of tiny particles called atoms?

John Dalton

Atoms are composed of three particles. Name the three and describe each one’s charge.

Proton-positively charged particleNeutron- uncharged particleElectron- negatively charged

particle

What type of charge does the nucleus of an atom contain?

Positive—why??

What specific type of metals fall under group 2?

Alkaline Earth Metal

This is a one or two letter code that is used to depict the name

of the element.

Chemical Symbol

True or False. The modern periodic table is organized by

only it’s category (metal, nonmetal, metalloid).

False. It is organized by atomic number

and by the properties of the elements.

How can you determine the # of neutrons in an element’s atoms?

Atomic Mass - Atomic Number(# of protons/neutrons - # of protons)

______ are atoms of the same element that have a different

number of neutrons.

Isotopes

When an atom gains one or more electrons we call it a ________

______.

Negative Ion

What part of the periodic table tells you the state of

matter at room temperature?

Chemical Symbol Color

What are the three basic categories on the periodic table

and how are they identified?

Metals, Non metals, and Metalloids. Color of the box.

How many electrons does a neutral Radon atom have? (Use

your textbook)86—how did you know this??

“Neutral” means it ha no charge, so if you found the # of protons (atomic number) you

know the # of electrons.

The atomic mass represents the number of protons in an atom’s

nucleus.

FALSE; Atomic number

The elements in group 1 are known as...

Alkali Metals

What is the atomic mass of the element found at Group 10, Period

4? (use textbook)

58.69- Nickel

The elements found in groups 3-12 are known as _________

_________.

Transition Metal

What is the atomic number of the element that is a liquid at room

temperature and can be found in the Halogen group?

35; Bromine – BrHalogen is group 17

What is the chemical symbol of the only element that is a metal, but is a liquid at room

temperature?

Hg- Mercury

161 NeutronsAtomic Mass - Atomic Number

269-108 = 161 Neutrons

How many neutrons does an average atom of Hassium

contain? (# of protons: 108)
