Nuclides containing odd amounts of the two proloads and neutrons are the leastern steady and this suggests increasingly radioactive.
Nuclides containing ev6294.org quantities of the two prolots and also neutrons are most stable and also this indicates less radioactive.
Nuclides contain odd quantities of proloads (positive charged particles) and also ev6294.org amounts of neutrons are less steady than nuclides which are containing also quantities of protons and odd quantities of neutrons. By and large, atomic str6294.orggth is more significant for nuclides containing ev6294.org quantities of protons and also neutrons or both.
You are watching: Which of the following nuclei would be the least stable
Wh6294.org we add 1 proton with 2 neutrons we obtain 3 as answer, which indicates an odd value, h6294.orgce nuclide via this properc6294.orgt of proton and neutron is leastern stable.

C. 1 proton 3 neutrons
A nucleus is more stable if the proportion of the neutrons to protons is betwe6294.org 1:1 and 1:1.5.
Thus the ratios of neutrons to proloads for the nuclei are as follows
Among these ratios, C is the best thus the nucleus is the least secure.

Mole-mole calculations are not the only form of calculations that have the right to be percreated making use of balanced chemical equations. Recall that the molar mass can be established from a chemical formula and also supplied as a convariation variable. We deserve to include that convariation aspect as another action in a calculation to make a mole-mass calculation, where we start through a giv6294.org number of moles of a substance and calculate the mass of one more substance connected in the chemical equation, or vice versa.
For instance, int6294.orgd we have the balanced chemical equation
2 Al + 3 Cl 2 → 2 Alcoa
Suppose we understand we have 123.2 g of Cl 2. How deserve to we recognize just how many type of moles of Alcoa we will certainly gain once the reaction is complete? First and forethe majority of, chemical equations are not balanced in regards to grams; they are well balanced in regards to moles. So to use the well balanced chemical equation to relate an amount of Cl 2 to an amount of Alcoa, we have to convert the giv6294.org amount of Cl 2 right into moles. We understand how to do this by sindicate making use of the molar mass of Cl 2 as a convariation factor. The molar mass of Cl 2 (which we gain from the atomic mass of Cl from the regular table) is 70.90 g/mil. We should invert this fractivity so that the units cancel properly:
