is for Carbon

Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.

is for Darmstadtium 

Darmstadtium is an atomic number 110 chemical element with the symbol Ds. It's a man-made element that's incredibly radioactive. Darmstadtium-281, the most stable isotope known, with a half-life of about 12.7 seconds.

is for Erbium

Erbium is a chemical element with the atomic number 68 and the symbol Er. When artificially isolated, erbium is a silvery-white solid metal, but it is always found in chemical combination with other elements in nature.

is for Iron

The chemical element iron has the symbol Fe and the atomic number 26. It is a metal that belongs to the periodic table's first transition series and group 8. It is the most abundant element on Earth by mass, just ahead of oxygen, and it makes up much of the planet's outer and inner core.

is for Gallium

Gallium is a chemical element with the atomic number 31 and the symbol Ga. Gallium was discovered in 1875 by French chemist Paul-Émile Lecoq de Boisbaudran and is similar to the other metals in group 13 of the periodic table. In ordinary pressure and temperature, this element gallium is a soft, silvery metal.

is for Hydrogen

Hydrogen is a chemical element with atomic number 1 and the symbol H. The element hydrogen is the lightest. Hydrogen is a gas made up of diatomic molecules with the formula H2. It's colorless, odorless, tasteless, non-toxic, and flammable.

is for Iodine

Iodine is a chemical element with atomic number 53 and the symbol I. At typical conditions, it exists as a semi-lustrous, non-metallic solid that melts to produce a deep violet liquid at 114 °C (237 °F) and boils to form a violet gas at 184 °C (363 °F).

is for Joke of the Day!!!

Are you hydrogen???

...

Why would I ask?

...

Because I can't live without you!

is for Potassium 

Potassium is a chemical element with atomic number 19 and the symbol K. Potassium is a delicate silvery-white metal that may be sliced with a knife with little effort. In mere seconds of exposure, potassium metal interacts with ambient oxygen to generate flaky white potassium peroxide.

is for Lithium 

Lithium is a chemical element with the atomic number 3 and the symbol Li. It's a silvery-white alkali metal with a delicate texture. It is the least dense metal and the least dense solid element under ordinary conditions.

is for Magnesium

Magnesium (Mg) is the lightest structural metal and one of the alkaline-earth metals of Group 2 (IIa) of the periodic table.

is for Neon

Neon is a chemical element with the atomic number 10 and the symbol Ne. It's classified as a noble gas. Under normal conditions, neon is a colorless, odorless, inert monatomic gas with a density of about two-thirds that of air.

is for Oxygen

Oxygen is a chemical element with the atomic number 8 and the symbol O. It is a highly reactive nonmetal and an oxidizing agent that rapidly produces oxides with most elements and other compounds. It belongs to the chalcogen group in the periodic table.

is for Phosphourus

Phosphorus is a chemical element with atomic number 15 and the symbol P. Phosphorus exists in two major forms: white phosphorus and red phosphorus, however it is never found as a free element on Earth due to its extreme reactivity.
