Is oxygen a solid or liquid?
Although oxygen gas is colorless, the liquid and solid forms of oxygen are blue.
What are the elements that make up the majority of the universe?
Helium and hydrogen make up most of the universe. Both of them account for 98% of all matter, being roughly 73% hydrogen, and 25% helium. All the other elements make up the remaining 2% of matter. The next in the list is oxygen, making up for a tiny 0.05%.
How old are hydrogen atoms?
This happened around 13.7 billion years ago! So the hydrogen atoms that make up your body are 13.7 billion years old.
Is glass a liquid or solid?
Glass is not a liquid; it is an amorphous solid. With amorphous we mean that it has no microcrystalline order. With solid we basically mean that you can grab it without losing its shape.
What is the most beautiful molecule?
The football-shaped carbon cluster C 60 has been called ‘the most beautiful molecule’, and if you have an eye for symmetry it’s easy to understand why. But if you ever liked chemistry in school, or actually have a career working in chemistry, you know chemistry goes beyond ‘beauty’.
What was the first element in the universe?
At ground zero, during the Universe’s singularity, the very first chemical element was hydrogen. All the other followed by fusing hydrogen into helium, which then fused into carbon and so on. Approximately 73% of the mass of the visible universe is in the form of hydrogen. Helium makes up about 25% of the mass, and everything else represents only 2%. By mass, hydrogen and helium combined make up less than 1% of the Earth.
How is Astatine made?
Named after the Greek word for unstable ( astatos ), Astatine is a naturally occurring semi-metal produced from the decay of uranium and thorium. In its most stable form, the element has a half-time of only 8.1 hours. The entire crust appears to contain about 28 g of the element. If scientists ever have to use it, they basically have to make it from scratch. Only 0.00000005 grams of astatine have been made so far.
Why are metals good conductors?
This is why metals are great electrical and thermal conductors — because the electrons move energy.
How old is every hydrogen atom in the human body?
5. Every hydrogen atom in your body is likely 13.5 billion years old because they were created at the birth of the universe.
Which metals absorb light?
Most metals’ electrons reflect colors equally, so the sun’s light is reflected as white. Gold and copper, however, happen to absorb blue and violet light, leaving yellow light. It’s worth noting here that copper is also the only metal that is naturally antibacterial. 3.
Is glass a liquid or solid?
In a glass, molecules still flow, but at a very low rate that it’s barely perceptible. As such, it’s not enough to class glasses as a liquid, but neither as a solid. Instead, chemists classify glasses as amorphous solids— a state somewhere between those two states of matter.
What are the two elements that are liquid at room temperature?
At room temperature, there are only two liquid elements. These are bromine and mercury.
What is matter made of?
All matter is made up of the chemical elements, which are distinguished from each other by the numbers of protons they possess.

Chemistry is the study of matter and energy and the interactions between them. It is a physical science that is closely related to physics, which often shares the same definition. Chemistry traces its roots back to the ancient study of alchemy.
What is the first element in the periodic table?
The first element in the periodic table is hydrogen. Each element in the periodic table has a one or two-letter symbol. The only letter in the English alphabet not used on the periodic table is J. The letter Q only appeared in the symbol for the placeholder name for element 114, ununquadium, which had the symbol Uuq.
Why is chemistry considered a rigorous A level?

What is the most common element in the universe?
The most common Element in existence is Hydrogen, which is also the first element listed on the periodic table. Hydrogen accounts for 74% of atoms in the universe, but despite this it wasn’t actually given a name until 1783.
What is a chemistry level?
A Chemistry A level is listed as a facilitating subject by the Russell group, meaning that it is one of the 8 subjects ‘most likely to be required or preferred for entry to university courses”. Studying Chemistry can give students the widest possible range of courses to study from, even for non-science degrees.
Who invented the periodic table?
The table as we know it was invented by a Russian scientist named Dmitri Mendeleev in 1869. One of 11, 14, or 17 siblings (history can’t quite agree on the specific number).
How many elements are in the periodic table?
Mendeleev was also notable for introducing the metric system to Russia and being a strong contender for “best mad scientist hair”. Unlike other attempts to create a periodic table, Mendeleev’s table allowed for gaps in the table, allowing for then undiscovered elements to be added as they were discovered. Originally, there were 56 elements detailed on the table. Today there are 118 elements listed in the table, although 4 are yet to be fully confirmed as they have only been created in a laboratory for milliseconds at a time.
The interesting thing about the chemical elements
Gallium was the prefix named after a rooster, whose work of discovering the prefix filled a position predicted by the chemist Mendeev.

What is the purpose of chemistry?
Chemistry studies matter and what it’s made of. It tells us how substances change and what properties they have. Chemistry seeks to answer questions such as: What is the Universe made of? How do elements react with each other?
What are the topics in advanced chemistry?
Once you’ve mastered chemistry’s fundamental concepts, you’re ready for the advanced part. Here, you will explore topics such as kinetics, equilibrium, and thermodynamics. Consult our list for 30 interesting advanced chemistry topics:
What is organic chemistry?
It seeks to understand the molecular structure and behavior of living beings. Inorganic chemistry focuses on materials rather than living beings. Chemists of this field aim to advance technology. Physical chemists examine the atomic level of matter.
How many branches of chemistry are there?
Chemistry is a broad subject that uses various methods of study. Because of this, scientists divide it into five main branches. These are organic, inorganic, physical, analytical, and biochemistry. Let’s investigate them:
Why is green chemistry important?
If you’re concerned with sustainability, green chemistry is your area of choice. It finds ways to make chemical products less harmful to the environment. Research is done at every stage, from the product’s design to its disposal.
What are some examples of chemical processes that occur in living organisms?
Have you ever wondered what chemical processes happen inside living organisms? Here’s an example: when we breathe, we inhale oxygen and exhale carbon dioxide. Biochemistry combines biology and chemistry to find out how life works on a molecular level. It’s a life science that deals with the cells, proteins, and lipids that form the core of every being. Clinical research highly benefits from biochemical knowledge.
