ATOMIC STRUCTURE AND BONDING 1

Question 1

What are the objects that make up an atom called?

Answer 1

Sub-atomic particles

Question 2

What are the three types of sub-atomic particles that we need to know?

Answer 2

Electrons, Protons, and Neutrons

Question 3

What is the charge for the sub-atomic particle called the electron?

Answer 3

Charge: -1

Question 4

What is the charge for the sub-atomic particle called the proton?

Answer 4

Charge: +1

Question 5

What is the charge for the sub-atomic particle called the neutron?

Answer 5

Charge: 0

Question 6

What is the relative mass of the three sub-atomic particles?

Answer 6

All are measured in AMU (atomic mass unit)
Proton: 1
Neutron: 1
Electron: 1÷1840 (almost nothing)

Question 7

What is an atom?

Answer 7

The smallest particles of matter, cannot be broken down further by chemical means

Question 8

Where can you find electrons?

Answer 8

orbiting around the nucleus in shells

Question 9

Where can you find protons?

Answer 9

In the nucleus of an atom

Question 10

Where can you find neutrons?

Answer 10

In the nucleus of an atom

Question 11

Bonus: What charge does a muon have?

Answer 11

Charge: -1

Question 12

What is another name for the number of protons?

Answer 12

Atomic number

Question 13

What is another name for the number of protons plus the number of neutrons?

Answer 13

Nucleon number (because they’re in the nucleus!)

Question 14

What is relative atomic mass?

Answer 14

also represented as A(r)
Relative atomic mass is the (average mass of isotopes of the element) ÷ (1/12 x mass of 1 atom)

Question 15

What is an ion?

Answer 15

An ion is an electrically charged particle that has either lost or gained an electron through one of the three types of bonding

Question 16

Bonus: Is the positive hydrogen ion a thing?

Answer 16

Yes it is, but it’s so minuscule that we only use it for calculations and it serves no purpose as it’s just a single positive charge

Question 17

What are the three types of bonding

Answer 17

Ionic bonding, Covalent bonding, and Metalic bonding

Question 18

What are isotopes

Answer 18

Isotopes are Atoms of the same element that have a different number of neutrons

Question 19

What are the 2 types of isotopes?

Answer 19

stable isotopes
and
unstable isotopes (also known as radioactive isotopes)

Question 20

What does radioactive mean

Answer 20

Radioactive means its nucleus is unstable, the atom will break down naturally/decay giving out radiation in the form of rays and particles, plus a large amount of energy
