About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life. ... The very heavy elements in you were made in exploding stars. The size of an atom is governed by th...
Atomsare the foundation of matter, which is everything that makes up the universe around us. Each kind of atom makes up a pure substance called an element. You may have heard of oxygen, lead, and gold. Well, these are all examples of elements. Can you believe that a pure gold ...
The sample of hydrogen has a mass of 1.01g,how many hydrogen atoms make up 1.01g? 3 英语翻译 What is the mass of one carbon atom in atomic mass unit(amu) What is the mass of one carbon atom in grams(g) What is the mass of one oxygen atom in amu? What is the mass of one ...
All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportion of oxygen atoms. Although the st...
The number of protons in an atom is unique to each element. For example,carbonatoms have six protons,hydrogenatoms have one andoxygenatoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons also determines the chemical be...
What atoms make up lipids?LipidsLipids are a type of molecule that do not dissolve in water, but can dissolve in other types of solvents known as non-polar solvents. Examples of lipids include fats and oils (these are the main lipids in your diet), and soap, such as you would use to...
Water forms when two hydrogens snap onto one oxygen. Chemical reactions like this make sense if the elements exist as simple building blocks: atoms, in other words. If we can't see atoms, how do we know they're there? That's a very good question! Science is all about evidence, so ...
What are atoms that carry an electric charge? What unit is used to measure atomic mass? What is a negatively charged atom called? What is the mass number of an oxygen atom with 7 neutrons? What is a group of atoms joined together called? What is the relationship between atomic mass and...
Oxygen is primarily absorbed through the lungs and carried throughout the body in blood cells. On the other hand, liquid oxygen bypasses the lungs & is absorbed directly into the bloodstream. Why? Because there are different types of oxygen atoms called isotopes, some do not have to be inhale...
An oxygen atom contains eight electrons, arranged into two orbital shells. Electron Situated within the two shells, these subatomic particles have a mass of almost zero and a charge of -1. Unpaired electron Two electrons in the outer shell don’t have a partner. This allows oxygen atoms to ...
