Unit 1 - Introduction to Earth and Space Science

What is the scientific definition of an atom? 

The smallest unit of any chemical element

what is matter?

Anything that has mass and takes up space

What is there nucleus?

The center of an atom

Where can electrons be located?

found in the space surrounding the nucleus

Where can protons be located

Located in the nucleus of an atom

What kind of charge do protons have?

Positive also affects amu also allow you to identify the element

What kind of charge do neutrons have

Contain a neutral charge but do affects the amu

What kind of charge do electrons have

Contain a negative charge and do not affect the amu

Where can neutrons be located

In the nucleus of a atom

How do you identify the number of neutrons

atomic mass - protons

What are isotopes

atoms with the same element with the same number of protons but a different number of neutrons

How do you find the amount of neutrons in a insotope

Take the mass number and subtract the amount of protons

What are most of the elements on the periodic table

Naturally a curing isotopes

How do you find the atomic mass

the average atomic mass is a weighted average of all the the naturally occurring isotopes of an element

How do you find the atomic mass of a newly discovered isotope

Take the elements number and multiply it by its chance to spawn in and add it with the other isotopes

What is a compound

A compound is made from 2 or more different elements that have been chemically conjoined(example water H20 and carbon dioxide ) 

What are groups

These are vertical columns on the periodic table

What are periods

Horizantal rows on the periodic table

Mass generally…

Increases across the periodic table

Atomic size generally…

Decreases across the periodic table

Metals are normally…

Good at conducting heat and electricity
