if you round the number to the nearest whole number you will find the mass number of the most common isotope. For carbon the mass number (M) is 12. This number is the sum of the number of protons and neutrons.
If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons?Answer and Explanation: The atomic number is equal to the number of protons in an atom. For ...
In the neutral, non-charged state, every atom has the same number ofelectronsas it does protons. Elements starting with helium also contain a number ofneutronssimilar to and usually slightly in excess of the proton number. Variants of elements with different numbers of neutrons are called isotope...
When the universe was 0.00001 seconds old, quarks combined to form protons and neutrons. When the universe was 0.01 seconds old, protons and neutrons began to organize into atoms. Finally, when the universe was the tender age of 380,000 years old, photons broke free, and light streamed acro...
How do you show the number of protons and neutrons on a Bohr-Rutherford diagram? How do you to convert polar to rectangular coordinates? Explain how ratio analysis can be used to evaluate a businesss ability to pay its debt? How can one prove that the exterior angles of polygon always add...
In the center of the atom, the protons and neutrons gather to form the nucleus, while the electrons zip around that nucleus as if they are minute planets orbiting their own little sun [source: Northwestern]. A human's body weighing 154 pounds (70 kilograms) is comprised of 7 billion ...
particle that orbits the nucleus of an atom. The nucleus consists of positively charged protons and neutrally charged neutrons. The number of protons in the nucleus defines the atomic number of an element, and the number of electrons in a neutral atom is equal to the number of protons. ...
How to find the number of protons in an isotope What is the mass number of an isotope? How to find isotopic mass What is the percent abundance formula? How can you calculate the number of neutrons (n) in an atom? What is the mass number of the isotope lithium-7?
When the universe was 0.00001 seconds old, quarks combined to form protons and neutrons. When the universe was 0.01 seconds old, protons and neutrons began to organize into atoms. Finally, when the universe was the tender age of 380,000 years old, photons broke free, and light streamed acro...
The atomic weight is the average mass of all the element's isotopes. It is the average number of all the protons and neutrons in the nucleus. Generally, the atomic mass increases as you move down or across each group or period. Of course, there are exceptions to this rule. Check out ...
