You only use the average atoimc weight with isotopes correct? One of the problems on MasteringChemistry asked what is the average atoimc mass of element X and gave four isotopes. I guess I was confused because I used the formula for average atoimc weight and got it wrong. Can we do one of those in lecture?
What else can I help you with?
Why is the structure of a nephron so difficult to determine?
The structure of a nephron is difficult to determine because a nephron is very small, and there are so many nephrons piled on top of each other that they are difficult to distinguish. A healthy human kidney has about 1 million nephrons.
Why is a diamond so hard?
Diamond's atomic structure makes it the hardest mineral known.
Have we fully determined the 3D structure of eznymes yet?
Determining the shape of a membrane protein is a very difficult task; however, very few scientists have succeeded in this endeavor. So, yes overall, we have been able to determine a few of the enzymes structures. If I am correct, there is even a game where you can determine the structure of enzymes; but, I cannot recall it's name.
How do scientists determine the number of neutrons and isotopes in an atom?
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
What information can you gather knowing the atomic number and mass of an element?
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
Can you determine the element with only knowing the number of protons?
The number of protons is the "atomic number", so you look that up in the periodic table.
Why would it be difficult to determine unknown liquids only be their flame tests?
no one knows That I am so sorry
Is a Mansard roof difficult to install?
A mansard roof is difficult to install due to its shape and structure. What makes a mansard roof so difficult to install is that there are 4 sides all of which have different slopes.
How can the atomic atom be used to determine the number of neutrons?
The atomic weight of any given isotope of an element is the result of the protons and the neutrons. The number of protons is the same as the atomic number, so if you subtract the atomic number from the atomic weight, voila, there is the number of neutrons. Bear in mind that elements have more than one isotope, and each isotope has a different number of neutrons. So the atomic weight is the result of a mixture of isotopes that appear in nature.
Determine the atomic mass for sodium?
23. Sodium (Na) has 11 electrons (it's atomic number) and so must have 11 protons, add in a neutron for good measure and we get 23. The atomic weight (not mass) of sodium is 22,989 769 28(2).
What does the atomic number tell you about the atomic structure of any element?
An atom contains Protons, Neutrons and Electrons the atomic number is the protons and neutrons combined, the number of protons in the atom is equal to the total number of electrons in the atom which are aranged in the outer shells at 2,8,8,8,8 and so on to find the totoal number of protons in the neucleus of the atom you take the atomic mass and minus the atomic number from it. so He or Helium is 4.0026 atomic mass and 2 for atomic number and so has 2 protons and so in turn has 2 electrons.
How do you determine the number of neutron's in an atom of a given element?
Atomic Mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
