What are four elements found in most compounds of the human body?
The four most abundant elements in the human body are:oxygen: 65%carbon: 18%hydrogen: 9.5%nitrogen: 3.2%There are many more elements than those listed, such as calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium.https://www.thoughtco.com/elements-in-the-human-body-p2-602188
What elements have more than one form?
Carbon, sulfur, and phosphorus are examples of elements that exist in more than one form. For example, carbon can be found as diamond or graphite, sulfur can be found as rhombic or monoclinic, and phosphorus can be found as white or red.
What has more protons carbon or copper?
Copper has more protons than carbon. Carbon has 6 protons, while copper has 29 protons. This difference in the number of protons is what distinguishes the two elements on the periodic table.
Is helium more abundant than argon?
Argon, Ar. 0.93. Carbon dioxide, CO2. 0.033. Neon, Ne. 0.0018. Helium, He. 0.00052. Methane ... much higher than it is in air. ... Argon is the most abundant and most used of the noble gases.
What are two atoms that are heavier than carbon?
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
What is the definition organic compound?
Compounds that contain mostly carbon and hydrogen.The basic building blocks of life which are carbon compounds which are more abundant than most elements on earth.
The most abundant elements in the body are what?
The most abundant elements in the human body are carbon, hydrogen, oxygen, nitrogen, phosphorous, sulfur, calcium, sodium, potassium, chlorine (don't forget, table salt is sodium chloride!) and iron. There are many others that are present in smaller quantities including copper, zinc, iodine, etc.
What is more on earth abundant carbon 12 or carbon 14?
Carbon-12 is more abundant on Earth than carbon-14. Carbon-12 is the most common and stable isotope of carbon, accounting for about 98.9% of all carbon atoms, while carbon-14 is a radioactive isotope with a much smaller abundance in the environment.
Which gas is more plus abundant in exhaled air than inhaled air?
Carbon dioxide (CO2).
Which element has two or more protons than carbon?
Nitrogen has one more proton than carbon with 7 protons.
Which elements cannot be extracted by heating with carbon?
Elements that cannot be extracted by heating with carbon include those that are more reactive than carbon, such as the alkali metals and alkaline earth metals. These elements require more powerful reducing agents for extraction, such as electrolysis.
What are the five most abundant elements in earth's atmosphere?
The five most abundant elements that make up atomic matter are; Hydrogen, Helium, Oxygen, Carbon and Neon. Hydrogen is by far the most abundant element. There is three times as much Hydrogen than the next most abundant element, Helium.

What gas is more abundant in exhaled air than inhaled air?
Nitrogen is the most abundant gas in the atmosphere ( ~ 80% ) and therefore is the dominant species in both inspired as well as expired air.
Is carbon more reactive than chromium?
Yes, carbon is more reactive than chromium. Carbon is a non-metal and easily forms compounds with other elements, while chromium is a transition metal that is more stable and less reactive.
Is carbon more reactive than boron?
Carbon is more reactive than boron. Carbon readily forms compounds with other elements due to its ability to form multiple bonds, such as in organic molecules. Boron, on the other hand, is less reactive and tends to form more covalent compounds with a limited number of elements.
What elements have more than one form?
Carbon, sulfur, and phosphorus are examples of elements that exist in more than one form. For example, carbon can be found as diamond or graphite, sulfur can be found as rhombic or monoclinic, and phosphorus can be found as white or red.
