2.  The element that I chose is Helium  In 1868 an English astronomer named Sir Norman Lockyer saw a weird yellow line in the sun and, he thought it was a new element. He called this new element helium.

3. What this picture shows is the name of this element, its atomic number (2), its symbol (He), and its atomic mass (4.0026)

4.  Electrons: 2  Neutrons: 2  Protons: 2

5.  Its melting point: 0.95 [or -272.2 °C (-458 °F)] K  Boiling point: 4.22 [or -268.93 °C (-452.07 °F)] K  Color: colorless  Texture: it’s a gas so no texture  Freezing point: none

6.  Helium is a noble gas  Helium has 2 valence electrons and it is in group 8

7.  Helium is found in the sun  Helium is 24 present of the universe mass

8.  Helium makes the a balloon rise because helium is 0.1785 grams and it is liter than Nitrogen which is 80% of air weighs 1.2506 grams  Helium makes your voice high  Helium is found in the sun and our universe

10.  You would want to buy it because it is funny when you have your voice high up and also you can blow up a balloon up more fun than the old fashion way by blowing air into it
