An element which will not combine chemically is

reactive
inert
non-chemical
a chemical

answer quickly and correctly

Option (b) is the correct answer.

Explanation:

When there will be completely filled orbital of an atom then it neither needs to lose or gain an electron in order to attain stability. This is because it is already stable due to completely filled orbital.

Therefore, it means that the element will be inert in nature.

For example, helium is a noble gas and its electronic configuration is .

As it has completely filled s-orbital so, it is stable in nature.

Whereas when an element does not have completely filled orbital then it needs to gain stability by gaining or losing an electron. This is what determines the reactivity of an element.

Thus, we can conclude that an element which will not combine chemically is inert.

answer; talc and gypsum;

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
