Unknown Story
Storyboard Text
- My teacher assigned me a project to make a storyboard on my story of gas and i have only today's night to complete it, leave it i will sleep now or else i will have headache.
- DREAMING ZZZ......
- HELLO So what should we play today?
- OK!
- Today we will not play today i will tell about a non metal with a O symbol and atomic number 8,classified as nonmetal, oxygen is a gas that we inhale i our body.
- Do you know that oxygen is colorless, odorless, and tasteless. It's usually purified by fractional distillation of liquefied air, but the element is found in many compounds, such as water, silica, and carbon dioxide.Oxygen is a nonmetal. It has low thermal and electrical conductivity, but high electronegativity and ionization energy. The solid form is brittle rather than malleable or ductile. The atoms readily gain electrons and form covalent chemical bonds.
- I learned a lot of interesting things about oxygen, Chemistry is the best. Thank you for sharing it to me
- You're welcome.
- Oxygen was the atomic weight standard for the other elements until 1961 when it was replaced by carbon 12. Oxygen made a good choice for the standard before much was known about isotopes because although there are 3 natural isotopes of oxygen, most of it is oxygen-16. This is why the atomic weight of oxygen (15.9994) is so close to 16. About 99.76% of oxygen is oxygen-16.
- Oh wow that was a superb dream i also got an idea how i can make my project now i will wake up early and make the project.
