About This Quiz
The periodic table of elements began in 1789, when a French chemist categorized 33 elements into gases, metals, nonmetals and earths. In 1829, a German chemist realized that the elements could be grouped into larger categories. In 1864, chemists began sorting the elements by atomic weight and by 1871, more chemists began tweaking and creating further versions of the table. The table that we're familiar with today is attributed to an American chemist, who created it in 1923. Scientists' journey into understanding life is never-ending, and as recently as 2016, elements have been added to the table.
As of 2016, there were 118 confirmed elements on the periodic table. It's full of solids, liquids and gases, but they're split up into categories like noble metals and noble gases and semi-solids and reactive liquids and nonmetals and metalloids and weird things like halogens and transuranic elements just to make things more complicated. The main thing to know is that the elements are listed by atomic number, which is the number of protons that can be found in the nucleus of that element's atom. For example, hydrogen—No.1—has one proton in its nucleus. Needless to say, hydrogen is the most abundant element in the universe and every living thing contains hydrogen. That's all the hints we'll give you for now. Let's see what you know on your own.
What is the symbol for oxygen?
Oxygen is the third-most abundant element in the universe, the second-most abundant element in the Earth's atmosphere, and the most abundant element in the Earth's crust. It could be considered the most important element on Earth.
Hydrogen is the most abundant element in the universe. What is its periodic symbol?
The periodic symbol for hydrogen is "H" and it has the atomic number 1, which means its nucleus has just one proton. It is the most abundant element in the universe and it's what the Sun is made out of. Water, H2O, is made up of 2 hydrogen atoms bonded to one oxygen atom, so you can find plenty of hydrogen in the ocean.
What is "Zr," which can be used to create a popular diamond alternative?
The periodic symbol for zirconium is "Zr," and it can form into zirconium dioxide (ZrO2), which is commonly known as zirconia and is a popular alternative to diamonds. Zirconia has a high optical density and is usually colorless.
What is the periodic symbol for helium, which is the second-most abundant element in the universe?
The periodic symbol for Helium is "He" and it is second only to hydrogen as most abundant element in the universe. It is atomic number 2, which means its nucleus has just two protons. It is used to inflate balloons and blimps.
