2. The metals are located on the left side of the periodic table.

What does the bottom blue row represent?

Those are the lanthanides and actinides. They don't fit nicely on the periodic table, so we've given them their own area.

1. Metals and non metals are divided by the staircase
2.left of the staircase=metals
a. Iron Fe, Silver Ag, Gold Au
3. 18 groups
4. Period 3=Si
5. It does not react (nonreactive (noble gas) )
6 Group 17 non-metals=Halogens

Why are the bottom two rows somewhat separated from the rest of the table?

1.) The staircase separates metals from non-metals.

How are new elements found, and what properties do they have to have to end up on the periodic table?

They need more than 116protons.

1. The staircase separates the metals from the non-metals.
2. The metals are located on the left side of the periodic table.
2a. Li: Lithium Hg: Mercury Ba: Barium
3.18 groups and 7 rows
4. Row or Period: #3
5. Inert means unreactive.
6. Group #17 non- metals are called Halogens.

I am confused why there is a section of two rows or periods that are separated from the main part of the periodic table. Are they a different kind of metal that makes them completely different from the rest of the table? Why could they not be another group on the main part of the table?

5) You explain inert as being unreactive, which is a trait of the "noble gases."

Okay, so your oval circles were kinda confusing. Hydrogen is an alkaline earth metal? Or is it with the orange group?

Do we have to know all of the different types of elements? For example, halogens or noble gases?

3. How many groups are there on the periodic table? (18 groups)
4. In what number row is silicon, Si, located? (Period 3)
5. What does inert mean? (unreactive)
6. What are Group 17 non-metals called? (Halogens)

What does Alkaline mean?
Also, how come Hydrogen is with the metals on the left side of the staircase?
For it to be a group like in your question #3 does it have to have a certain amount of elements in it?

1. the metals from the non-metals
2. the left
a. Iron (Fe), Silver (Ag), Gold (Au)
3. 18 groups
4. Si is located in group number 14.
5. Inert means unreactive.
6. Halogens

What do elements in the same periods have in common?

I also do not understand what the bottom rows are and why they are separated.
