Question 23

What is an atom?

Answer 23

An atom is the smallest substance that consists of charges of protons, neutrons and electrons.

Question 24

Atom facts

Answer 24

Very small about 0.1 nano meter in radius had no electrical charge. Also are the smallest element known.

Question 25

what are Protons?

Answer 25

Are Positive charged subatomic particles in the nucleus with a +1 atomic mass unite.

Question 26

what are Neutrons?

Answer 26

Are subatomic particles in the nucleus with no charge and has 1 atomic mass unite.

Question 27

What is electrons?

Answer 27

Are subatomic particles with a negative charge found in the outer shell and has a atomic mass of -1

Question 28

Why do atoms have no charge?

Answer 28

As a atom as the same number of positive protons as negative electrons.

Question 29

What is an element?

Answer 29

The simplest type of pure substance is an element. They are substance that cannot be chemically be broken down into separate parts. E.G. Iron and sulfure both elements. Once they are purified they cannot be chemically separated into simpler substances.

Question 30

What is the atomic number?

Answer 30

The number of only protons in a atom.

Question 31

What is the mass number?

Answer 31

The number of both protons and neutrons in the nucleus of an atom.

Question 32

What is electron configuration?

Answer 32

Is numbers and dots showing the decision of where electrons are located/ organised in the outer shells/shell of an atom.

Question 33

What is Valance electron and electron shell?

Answer 33

Valance electron are the electrons in the outer most shell. Valance shell is the most outer shell in an atom.

Question 34

What is an ion?

Answer 34

Is an charged atom, meaning it has more electrons or protons if more electrons its negative if more protons its positive

Question 35

What is the diff between atoms and ions?

Answer 35

An atom is neutral with the same number protons and electrons. An ion is charged with ether more protons making it positive or electrons making it negative.

Question 36

Why do some atoms become ions?

Answer 36

Atoms want a full outer shell in order to do that it needs to take or remove electrons. Always done with another atom.

Question 37

How to name ions?

Answer 37

If its a metal put ion after the metal name like iron ion. For non-metals put ide by replacing the letters at the end like oxide or nitride.

Question 38

What determines if a atom will lose or gain electrons?

Answer 38

The number of electrons in the outer shell if 1,2,3 it would lose as its easier if 5,6,7 it gains as that's easier.

Question 39

What are groups in the periodic table?

Answer 39

Goes from top to bottom and are in groups according to the number of electrons in the outer with group one having one in the outer shell valence shell.
