What is the isotope of atom?
An isotope atom of an element is one with the same number of protons in the nucleus (i.e the atomic number) but with a different number of neutrons giving it a different mass. Isotopes have the same chemistry because they have identical valence shells. An example is chlorine which is found in nature with two stable isotopes 35Cl with 18 neutrons and 37Cl with twenty. As 35 is around 75% and 37 25% in nature the atomic weight is 35.453.
Can you find out the number of electrons by adding protons and neutrons?
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.
If one isotope of carbon has 6 protons and 6 neutrons The number of protons and neutrons of a second isotope of carbon would be 6 and 6 7 and 7 6 and 7 or 7and 6?
It would be 6 and 7. Here is why.... The isotope is created when you add a neutron. Protons cannot be added or taken from an atom or it changes the element entirely. Therefore, if you have carbon (6 protons & 6 neutrons) and you add a NEUTRON, you now have the 2nd isotope of carbon. I am positive that you cannot add protons to an atom. The one I am most familiar with is hydrogen. Hydrogen has one proton & ZERO neutrons. If you add one neutron you have deuterium which is the second isotope of hydrogen. If you add two neutrons you have Trittium...... By adding neutrons you have different variations of the SAME ELEMENT! If you added protons to the atom you would have DIFFERENT ELEMENTS! Hope this helps.
What is the mass of a potassium atom with 20 neutrons?
Mass number = No. of protons + No. of neutrons = 19 + 20 = 39
What is indicated by the sum of protons and the neutrons?
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
How many subatomic particles does krypton have?
Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
Radioactivity is a characteristic of elements with what atoms?
Radioactive elements are ones that have too many or two few protons and/or neutrons to achieve stability. For any normally stable isotope, adding or removing neutrons will make a different isotope, and can easily result in an unstable nucleus.

How is the mass of atom found?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

How many protons and neutrons in Cl-37?
The number of protons in Chlorine is relative to its atomic number of 17. The amount of protons will not change, or will become a different element. The 37 refers to the amount of nucleons in the element. The total nucleons is calculated by adding the amount of protons and neutrons, so if we know there are 17 protons, 37-17= 20 neutrons. There are 17 protons and 20 neutrons in Cl-37.
What element results if you add a pair of protons to the nucleus of mercury?
Assuming that two neutrons and two electrons are also added, the atomic number would shift from 80 to 82, resulting in lead. If the neutrons or electrons were not added, it would be the radioactive isotope, lead-206.
What makes up the mass of atoms?
Protons and neutrons are the primary contributors to an atom's mass. Electrons make up an insignificant amount of mass. Atomic mass is determined by adding the number of protons and neutrons in a nucleus.
What effect would adding additional neutrons have on the force in a nucleus?
The additional neutrons don't exert electric forces. They do attract one another, and the protons, via the strong nuclear force.
