Unit 1: Atomic Structure and The Mole

Atomic Structure

100

This is the positive charged particle in the atom

a proton

200

This is the word used to describe a charged atom

an ion

300

This is the Acronym used to help with determining the amount of subatomic particles in an atom

APE MAN

400

If I don't know the number of neutrons in an atom I can do this to quantify the amount

I can subtract the number of protons from the mass

500

I have an atom with a mass of 24 and a charge of +1 these two missing pieces of information could be used in order for me to determine the identity of the element

the protons and electrons

AAM

100

The mass of an element can change because of the variance of this subatomic particle

the neutrons

200

This is known as the percentage of the different isotopes needed for calculating the average atomic mass

The abundance

300

This type of average utilizes the percentage and the mass of each isotope to find the average atomic mass.

A weighted average

400

The average atomic mass should be really close to the isotope that has this when calculating the mass

The one with the highest abundance.

500

In order for you to find the abundances of 2 isotopes when you are given the average mass as 54.1g and the masses of 54 and 56. These are the 2 equations you need to utilize?

x + y = 100

54x + 56y = 54.1

The Mole

100

This man is credited with identifying the number of particles representing one mole of a substance.

Amedeo Avogadro

200

The mole is this type of word similar to dozen or ream

A grouping word to represent an amount of something

300

This is the number of atoms in one mole of any substance

6.02 x 10²³

400

Every time you increase or decrease an exponent by 1 you are effectively doing this

Changing the number by a factor of 10 or moving the decimal 1 digit

500

One mole of carbon atoms and one mole of iron atoms contain the same number of atoms, but they do not have the same value for this measurable property.

Mass

Mole Conversions

100

I'm smart and I don't need Desmos to know that a fraction is simply this type of mathematical function 

I divide the top number by the bottom number duh because I'm super smart.

200

Dimensional analysis is a scientific buzz word used to explain that you are mathematically doing this

Multiplying fractions or unit conversions

300

Dividing a unit by the same unit accomplishes this goal.

Cancels them out or eliminates like terms.

400

Converting from grams to moles requires the use of this conversion factor.

The Molar Mass

500

This is the number of moles contained in 1.81×10²⁴ atoms.

3 moles
