Which element is almost twice as abundant by mass as hydrogen in the human body?
Element composition of the human body: 65% Oxygen 18% CARBON 10% Hydrogen 7% All other elements
Where are molecules in the body?
You will find cells in any living thing or person.
Which element is present in all the large macromolecules in the human body?
All the macromolecules in the human body are basically Carbon covalently bonded to other elements- mostly Hydrogen, Oxygen and other carbon atoms. There are other elements, but they don't appear in all of the body's macromolecules.It is Carbon.
What is the most abundant element found in the human body?
Oxygen is element that is found in the highest percentage by weight in the human body. The body consists of 65% oxygen, 18% carbon, 10% hydrogen, 3% nitrogen, 1.5% calcium, 1% phosphorus, and other elements with increments of less than 1%.
What are three facts about elements?
Elements are the building blocks of matter. All atoms of the same element have the same atomic number. The mass number of atoms of the same element can vary.
Which element is present in all large mocromolecules in the human body?
carbon
Which element is presented in all the larges macromolecules in the human body?
Carbon.
In any element all atoms are what?
All the atoms have the same number of protons (element type).
The number of these must be the same for all atoms of an element?
The number of protons is identical in all atoms of an element.
Which element is present in all the large macramolecules in the human body?
Carbon and/or hydrogen.
What element makes up 63 percent of the human body?
Oxygen is about 63% of the human body by mass. Oxygen is in many biological molecules, but most of it is in water. Numerically, hydrogen atoms represent 63% of all atoms in the human body. That varies too, because many of the hydrogen are abound up in water and water content varies. Water by itself can be 63% of the mass of a human. (It varies with age, gender, muscle and and body fat, but is 55-65% for adults and more for children.) As one can see, many things are 63% of the human body.
Are molecules in your body?
Yes, there are atoms in everything, including the human body, inside and out. Everything that you can see is composed of atoms.
What are All the Atoms in argon?
Argon is an element and all the atoms in argon are argon atoms.
Which kind of an atom present in human body?
The human body is about 70% water which is H2O, so most of the atoms are hydrogen. But hydrogen atoms are very light, so by weight, most of the atoms are oxygen. By weight, the human body is 65% oxygen, 18% carbon, 10% hydrogen, 3% nitrogen, 1.5% calcium and 1.2% phosphorus. Those 6 elements account for over 98% of all the atoms in a human body.
All Atoms Of An Element Are Exactly?
All atoms of the same element are not identical. The atoms of same element with different number of neutrons are called as isotopes. Although, the number of protons and electrons are same in every atom.
Why do all atoms of an element have the same chemical prperties?
Because they are all the same type of atoms. Oxygen is an element. If you have 10 oxygen atoms, they will all behave like oxygen, since they are the same element.
Can atoms be found in the human body?
Yes, all matter is made up of atoms - both living things and inanimate objects.
