How many compounds exist in amino acids?
There are 20 naturally occurring amino acids found in living things.
How many electrons does the heaviest naturally occurring element have?
The heaviest naturally occurring element is uranium, and it has 92 electrons.
How many isotopes of elements x exist?
Different elements have between 0 and 10 naturally occurring isotopes, and between about 3 and 25 if you also include artificially prepared and characterized ones.
What element is an example of a homogenous mixture?
No element is a mixture of any chemical type, because by definition an element is a chemical substance that can not be broken down into simpler substances by chemical means. However, many elements can be separated by physical means into isotopes that differ from one another in atomic number. If these are considered mixtures, then many naturally occurring elements can be considered homogeneous mixtures. The element of lowest atomic number that has more than one stable isotope making up at least 5 % of the naturally occurring atoms is lithium, and the next lowest such element is boron. The next lowest such element is magnesium, which has three isotopes all satisfying this criterion. Titanium, with atomic number 22, has five such isotopes. Zinc, element 30, has five naturally occurring isotopes, three of which constitute more than 15 % each of the atoms in naturally occurring zinc. Germanium naturally contains five isotopes, each of which constitutes at least 5 % of the atoms, and 3 of these isotopes constitute at least 20 % of all the atoms each.
What are the different types of atoms that make up all of the naturally occurring substances?
They are different kinds of atoms, plain as that Various numbers of protons, electrons, and neutrons that make them all different and have various properties There are many types of atoms such as Metals, Nonmetals, Metalloids, Noble Gases, Radioactive, Transition Metals, and such
How many atoms of 124Sn are present in 12.0 g of naturally occurring tin?
The number of atoms is 0,035.10e23.
How many types of natural atoms are there?
There are 90 naturally occurring types of atoms, or elements.
How many protons electrons and neutrons are in boron?
All boron atoms contain 5 electrons and 5 protons. Atoms of the most abundant naturally occurring isotope of boron contain 6 neutrons each, and atoms of the only other naturally occurring isotope of boron contain 5 neutrons each.
How many compounds exist in amino acids?
There are 20 naturally occurring amino acids found in living things.
How many naturally occurring isotopes are in curium?
Practically none, though it seems plausible that trace amounts of Cm-247 exist in uranium ore.
How many electrons does the heaviest naturally occurring element have?
The heaviest naturally occurring element is uranium, and it has 92 electrons.
Why is the Gaussian distribution referred to as normal distribution?
Because many naturally occurring variables were approximately distributed according to a Normal bell shaped curve.Because many naturally occurring variables were approximately distributed according to a Normal bell shaped curve.Because many naturally occurring variables were approximately distributed according to a Normal bell shaped curve.Because many naturally occurring variables were approximately distributed according to a Normal bell shaped curve.
