Answer 2

Protons

Neutrons

Electrons

Question 3

What are the Charges of each Atomic Particle

Answer 3

Each Proton has a Positive charge

Each Neutron has a Neutral charge

Each electron has a Negative charge

Question 4

Explain the location of each atomic particle

Electrons buzz around the orbit of the nuclei

Question 5

Explain how an element is defined

Answer 5

An element is defined by the number of protons in their atoms.

Therefore, you can change the number of Neutrons and Electrons. But, if you change the number of protons, the entire element is changed.

Question 6

Define Isotopes

Answer 6

Isotopes are variants of a particular chemical element that differ in Neutrons.

Question 7

How do you Reperesent Isotopes

Answer 7

First you write the element symbol

On the left hand Subscript, you write the number of Protons

On the left hand Superscript, you write the combined number of protons and neutrons

Question 8

How do you represent isotopes using Hyphen Notation

Answer 8

You Represent Isotopes by writing the entire chemical name as stating the total numbe of Protons and Neutrons after the hyphen

(Carbon-12)

Question 11

Explain what an Element is

Answer 11

An element is a pure substance.

It cannot be broken down by any chemical means because
