Question

Lesson 02.02: Properties of the Atom
• Describe the properties and locations of protons, neutrons, and electrons in an atom.
• Explain what the mass number and atomic number identify about an atom.
• Use mass and atomic number to determine the number of each subatomic particle in an atom.


Lesson 02.03: Isotopes and Weighted Averages
• Identify the differences between isotopes of an element.
• Calculate the weighted average mass of an element when given the percent abundance and mass of its isotopes.

Answer 1

Fast question: you know all this right, we just recap it?

Answer 2

yes i already know this! this is just review... I promise!!

Answer 3

No it is more because if it is then I see no reason why you don't make the work and tell me about the properties and locations for
Protons:
Neutrons:
Electrons:
(might be a good way to remember it as you do an effort your self instead I just explain it)

Answer 4

Then I check if they are correct.

Answer 5

or something missing,

Answer 6

Protons and neutrons are in the center of the atom, making up the nucleus.
Electrons surround the nucleus.and have a negative charge.
Protons have a positive charge.
neutrons have a no net charge

Answer 7

Perfect so far :)

Answer 8

Think I go though the rest:
Explain what the mass number and atomic number identify about an atom.
Standard notation:
\[\LARGE _{Z}^{A} \left[ element \right]\]
Z = number of protons = number of electrons = atomic number
A = nucleon number = Z + N
N = number of neutrons.

Identify the differences between isotopes of an element:
Elements: Atom with a specific amount of protons.
Isotopes: Elements with different nucleon number. (Z = constant) AKA N (the number of neutrons change).

Calculate the weighted average mass of an element when given the percent abundance and mass of its isotopes.
