which element is least likely to undergo a chemical reaction
People also ask
What is the most reactive metal on the periodic table?
Ag, Au, Pt, Hg. The most active metals are so reactive that they readily combine with the O 2 and H 2O vapor in the atmosphere and are therefore stored under an inert liquid, such as mineral oil. These metals are found exclusively in Groups IA and IIA of the periodic table.
What are the factors that do not affect equilibrium?
For the chemical reaction: First, consider a factor that does not affect equilibrium: pure substances. If a pure liquid or solid is involved in equilibrium, it is considered to have an equilibrium constant of 1 and is excluded from the equilibrium constant.
How do you know which element will lose an electron?
We can decide which element should lose an electron by comparing the first ionization energy for potassium (418.8 kJ/mol) with that for hydrogen (1312.0 kJ/mol). Potassium is much more likely to lose an electron in this reaction, which means that hydrogen gains an electron to form K + and H – ions.
Are reactants and products always equal in a chemical reaction?
The quantities of reactants and products have achieved a constant ratio, but they are almost never equal. There may be much more product or much more reactant. Dynamic equilibrium occurs when the chemical reaction continues to proceed, but a number of products and reactants remain constant.
