Periodic Table

Question 1

What’s are the groups in a periodic table?

Answer 1

The horizontal columns of elements. Elements within a group share several properties. The Roman numerals above each group are the usual number of valence electrons the element has (outer electrons)

Question 2

What is a Periods on a periodic table

Answer 2

Vertical rows of elements, the period number of an element signified the highest unexpired energy level of an electron in that element

Question 3

Describe a metal

Answer 3

Shiny, solid at room temperature (expect Mercury), good conductor of heat and electricity, malleable , ductile, High melting point

Question 4

Describe a non metal

Answer 4

Dull, solid or gas at room temperature (except bromine) doesn’t conduct heat or electricity (insulator), not ductile, brittle, low melting point

Question 5

What is a transition metal

Answer 5

Ductile good conductors, there valence electrons or the electrons they used to combine with other elements are present in more than one shell. High density and melting point used a catalyst

Question 6

What is a noble gas

Answer 6

Colourless, odourless, tasteless, nonflammable gas. They all conduct electricity, have a complete outer shell, low boiling points and exist as single atoms (6 noble gases)
