Calculate the number of neutrons in a bromine nucleus, which has a radius of approximately 5.38 x 10-15 m. The atomic number of carbon is 6, the atomic number of chlorine is 17, and the atomic number of bromine is 35. What is the total number of atoms (not molecules) present ...
Determine the number of valence electrons in each of the following substances. (Note: Add one extra electron to the valence total for the substance in C because of the -1 charge on the polyatomic ion.Determine the following information for oxygen. ...
Note that the mass number of lithium is 6.94, representing the sum of the numbers of protons and neutrons in the nucleus of one atom. Step 3 Note that the mass number is equal to the mass (in grams) of one mole of lithium; this is the molar mass of lithium.Determine the Molecular ...
the researchers were looking to determine how many neutrons could be added to a nucleus before they stop sticking to one another, leading to dripping out. Such a limit is known as the dripline. Prior researchers have already found the dripline for a number of elements—all eight...
Use a periodic table to determine the atomic mass and the number of protons, electrons, and neutrons for neon.Mass Number:The mass of an atom always consists in the nucleus and it is equal to the sum of proton and neutron that is present in the nucl...
Answer to: To determine the age of rocks, the decay of which radioactive element(s) can be used? a) carbon-14 b) phosphorus-40, uranium-234 By...
A lewis structure is used to represent the structure of a molecule. Formal charges must be minimized in a lewis structure. Negative formal charges are placed on more electronegative atoms. Answer and Explanation:1 Drawing the lewis structure for thionyl chloride, we get....
It is a minor substance that is present in the element. Each atom has its specific symbol, number, and mass. Atom is present in the matter. Electrons present in the atom revolve around the nucleus. Neutrons and protons...
all nuclei that contain an odd number of protons and/or neutrons (in other words: nonzero nuclear spin) (most frequently used are 1H and 13C), and it means that at a characteristic and specific resonance frequency it comes to the absorption and re-emission of electromagnetic radiation [63]...
