The Periodic Table

Question 1

What is the periodic table (4)

Answer 1

• everything on different materials
• some are pure and some are compounds
• we can use the knowledge of the properties to make new materials
• properties have certain purposes

Question 2

How is the periodic table system used (3)

Answer 2

• the system is used to group and classify elements
• in different groups and colums
• only some are found pure in nature

Question 3

What is an atom ((4)

Answer 3

• it’s the smallest unit/ partical of matter
• the neucleus has protons (+)
• and neutrons (no charge)
• as well as electrons orbiting the core (-)

Question 4

What is a neutral atom (5)

Answer 4

• also known as a balanced atom
• where the number of protons and electrons are the same
• thus the charge is neutral
• the neutrals can differe from the the protons + electrons
• there are various factors to distinguishing atoms

Question 5

Name + discuss the factors of an atom (6)

Answer 5

• number of protons
• number of neutrons
• number energy levels
• number of electrons on the outer level
• determine chemical properties
• information is given by the periodic table

Question 6

Name the rows + collum placements (3)

Answer 6

• the horizontal rows = groups
• tge vertical collums = periods
• where element is placed gives a lot of information

Question 7

What does the groups tell us (3)

Answer 7

• The amount of electrons in the outer level
• can determine the chemical characteristics
• e.g. what elements they bind with

Question 8

What do the periods tell us (2)

Answer 8

• how many energy levels there are

- same period +/- same atomic mass

Question 9

Explain the •name (1)
•abbreviation (2)
•atomic mass (2)
of an element

Answer 9

Name
 •usually under symbol
Symbol 
• and abbreviation 
•in English or Latin
Atomic mass
• mass of the protons+neitrons
•electrons mass so small it’s not omitted to the final weight

Question 10

Discuss the atomic number ((6)

Answer 10

• It’s the number of protons in the neucleus
• it’s a good indicator of the number of electrons in the electron cloud of balanced atoms
• electrons are so unstable
• therefore they jumps/ change onto other atoms creating ions (atoms with charge)
• the protons and atomic number will always be the same
• a hydrogen has have 1 electron

Question 11

What is electron configurations (6)

Answer 11

• the way the electrons are placed in the energy levels
• each element is unique
• the first level always has two
• exept Hydrogen that only has 1 electron
• the strive to have 8 (to be completed)
• you fill from the inside out

Question 12

Discuss binding (3)

Answer 12

• if it’s in groups seven it is incompleted
• it would want to bind to be completed
• with the same or a different element

Question 13

Explain noble gasses (3)

Answer 13

• atom strive fill level up to 8
• group 8 atoms have 8 electrons
• wouldn’t want to bind

Question 14

Which groups can easily bind + explain (3)

Answer 14

• group 7 + 1 will bind easily
• they add up to eight
• need 8/ multiple of 8 for a stable mollicule

Question 15

Explain mollucels (5)

Answer 15

• 2 atoms can bind with 1 atom
• to get the total of eight
• e.g. Water
• 2 hydrogen + 1 oxygen + H2O(1 water mollucle)
• this is a chemical equation
