 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.

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

 Electrons: 2  Neutrons: 2  Protons: 2

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

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

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

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

 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
