The periodic table of elements is divided into two groups of elements

Chemistry

The periodic table of elements is divided into two groups of elements. Name those two main groups. 2. In video segment 3B, you are expected to sort periodic table cards and label a blank periodic table. Make sure that you sort the cards while working on video 3B. Which unknowns are gases? 3. As you look down the column of gases, what pattern do you see in the melting point and density?

1. Metals & Non Metals

2. The list of gases in the periodic table are the following: 

Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, and noble gases like Helium, Neon, Argon, Krypton, Xenon and Radon.

Just look for the following gases in the video segment.

3. Melting point and density of gases increases as we move down a group from top to bottom.

 

 

Step-by-step explanation

1. The periodic table is divided into two main groups which are Metals and Non Metals. 

 

2. The gaseous element group in the periodic table are Hydrogen (H), Nitrogen (N), Oxygen (O), Fluorine (F), Chlorine (Cl) and the noble gases like Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) and Radon (Rn).

 

3. As the atomic number in the periodic table increases, the density of the element increases. Same with the melting point, it increases as we move down the periodic table because the bonding and number of electrons also increases.
