Periodic Table

Question 1

The periodic table is for?

Answer 1

Arranging elements

Question 2

How does the periodic table arrangement help chemists?

Answer 2

It helps predict what chemical reactions that are likely for an element

Question 3

The periodic table has both metals and non metals. Label them on a periodic table now!

Answer 3

.

Question 4

Ask how an element can be determined to tell if it’s metal or non metal

Answer 4

.

Question 5

What is a vertical colum of elements called in the periodic table?

Answer 5

Groups

Question 6

What is a horizontal row called in the periodic table?

Answer 6

A period

Question 7

In what way are elements in the same group similar?

Answer 7

Similar chemical properties

This is because Atoms have the same number of electrons in the highest occupied energy level

Question 8

What are the names of the following groups?
Group 1
Group 2
Group 7
Group 8/0
Area between groups 2 + 3

Answer 8

Group 1 -alkali metals except hydrogen
Group 3,4,5,6 - alkaline earth metals
Group 7 halogens
Group 8noble gases
Between 2 and 3 transition metals

Question 9

Name the group which contains-
Very reactive metals
Very reactive non metals
Very unreactive non metals

Answer 9

Reactive metals - group 1 alkali metals
Very reactive non metals - group 7
Very unreactive non - metals - group 0 (eg helium)

Question 10

The transition metals are an important group of metals with a wide number of uses

Answer 10

.

Question 13

What is at the centre of every atom?

Answer 13

Protons and neutrons

Question 14

Where are the electrons located in an atom

Answer 14

Shells or orbitals that surround the nucleus of an atom

Question 15

What are the charges in each of the sub-atomic particles?

Answer 15

Protons- positive
Neutrons -neutral/no charge
Electrons - negative

Question 16

Why are atoms neutral?

Answer 16

Atoms have equal electrons and protons

Question 17

What mass do each of the sub-atomic particles have

Answer 17

Proton 1
Neutron 1
Electron (very small) 1/1836

Question 18

What is used to put the elements in order in the periodic table

Answer 18

Elements are arranged from left to right and top to bottom in order of increasing atomic number
Order generally is based with atomic mass

Question 19

What is the atomic number ?

Answer 19

The atomic number or the proton number of a chemical element is the numbers of protons found in the nucleus of an atom

Answer 21

.

Question 22

How can neutrons in an atom be calculated?

Answer 22

Mass number takeaway atomic number

Question 23

Where are electrons located and arranged with atoms?

Answer 23

Located in energy levels outside the nucleus and they have a 2,8,8,2 arrangement for the first 20 elements.

Question 24

What is the maximum number of electrons that each of the first 3 electron shells hold?

Answer 24

18 electrons

Question 25

What can be said about the number of electrons in the outer shell of the atoms of elements in the same group of the periodic table?

Answer 25

Has same number of electrons on outer shell

Question 26

Question 31

What’s an ion

Answer 31

Ion an imbalance of electrons and protons
Atom which loses or gains an electron
This creates an imbalance in charge
