Flashcards in Chapter 2 Structure Of Matter (Bushong) Deck (16):
1

What are the three fundamental particles of atom

Proton, neutrons, electrons

2

Which atomic particles are found in the nucleus

Protons and neutrons

3

What is the electrical charge of a proton

Positive

4

What is the electrical charge of a neutron

Neutral

5

What is the charge of an electron

Negative

6

What is the ideal charge of an Atom

Zero, electrically neutral, no charge. Electrons and protons cancel each other's charges out

7

How does the charge of an atom become positive

It loses an electron

8

How does the charge of an atom become negative

The atom gains an electron

9

What is a negative ion

Negative ions are created when a molecule gains a negatively charged electron

10

What is a positive Ion

Positive ions are created when a molecule gains a positively charged electron

11

Defined binding energy

The energy that holds an atom together

12

The electronic binding energy depends on what

Proximity to nucleus

13

Where is the binding energy the strongest

closest show to the nucleus

14

When is binding energy the weakest

In the farthest shell from the nucleus

15

How are you electron shells named

Starting K closest to the nucleus and ending at P, going alphabetically.

16

How many electrons can the outer most shell hold
