CC 1: The Nucleus

Question 1

A well-tested set of ideas that explains many disparate observations

Answer 1

Theory

Question 2

The random motion of particles suspended in a medium is called…

Answer 2

Brownian motion, or pedesis

Question 3

Number of protons and neutrons in an element

Answer 3

Mass number

Question 4

What is the atomic mass

Where is it located on a chemical symbol

Answer 4

Average of all isotopes (Mass Number) of an element

Below the atomic symbol

Question 5

What serves as a buffer between all the positively charged Protons in the nucleus. To prevent them from repelling eachother

Answer 5

Neutrons

Question 6

What is an Isotope

Answer 6

Elements with different numbers of neutrons, hence different mass numbers

Question 7

What are nucleons

Answer 7

Protons and neutrons

Question 8

What are the 2 numbers on the upper left side of an element

Answer 8

Top number = Mass number (Protons & Neutrons)

2nd Number = Atomic Number

Atomic Number will always be smaller

Question 9

Atomic mass vs Mass number

Which is located on the periodic table

Answer 9

Atomic mass = Average of all isotopes Found on the periodic table

Mass number = number of Protons & Neutrons in a specific atom
