Periodicity

Question 1

What is the periodic table

Answer 1

A list of all the elements in order of increasing atomic number, you can predict the properties of an element from its position in the table

Question 2

What blocks are the elements sorted into

Answer 2

s-block, p-block, d-block, and f-block- based on the orbital of their highest energy electrons

Question 3

What is a group

Answer 3

A vertical column of elements, they form a chemical family and have similar properties

Question 4

What are the reactivity trends in the table

Answer 4

In the s-block, elements get more reactive going down a group, to the right (non-metals), elements get more reactive going up a group,
Transition elements are rather unreactive,
Lanthanides all tend to form +3 ions and have similar reactivity,
Actinides are radioactive,

Question 5

What is a period

Answer 5

Horizontal rows of elements
