Atomic Structure & The Periodic Table

Question 0

What is the charge on a proton a neutron and a electron??????

Answer 0

Neutrons - 0
Protons- +1
Electrons- -1

Question 1

Where in the periodic table do you find: 
 Noble gases 
 Alkali metals 
 Halogens 
Metals 
 Non metals 
Transition metals

Answer 1

noble gases = group 0
Alkali metals = group 1
Halogens = group 7
Metals = left
Non metals = right
Transition metals = from Rf to Hg (middle)

Question 2

What is an atomic number and a mass number?

Answer 2

• Mass number is the top number of an atom which is the mass of its electrons and neutrons.⬆️
• atomic number (proton number) the amount of protons in a atom the bottom number.⬇️

Question 3

How are atoms arranged in the periodic table?

Answer 3

They are arranged in by there atomic number :)

Question 4

How are the electrons arranged inside an atom?

Answer 4

They are in shells first shell can hold 2 
Second can hold 8
3rd can hold 8 
4th can hold 8 
5th can hold 8 
6th can hold 8
7th can hold 8 
8th can hold 8

Question 5

Why are the atoms of group 0 elements so unreactive?

Answer 5

They have a full outer shell

Question 6

How is the number electrons in the outer shell of an atom related to its chemical properties?

Answer 6

The amount of electrons on the outer shell decided of how reactive it is

Question 7

How do metals and non metals bond to each other?

Answer 7

Metals form positively charged ions and non-metals from negativity charged ions They react together making compounds which is called ionic bonds( opposite attract each other )

Question 8

How do non metals bond to each other?

Answer 8

It is called covalent bond ( more information on page 141){by sharing electrons}

Question 9

How do we write the formula of a compound?

Answer 9

For Magnesium Mg2+ & chlorine Cl- to join together you need 2 chlorines to make the equation balanced. MgCl2
