It has a full outer shell of electrons.
The element that fits this description is neon (Ne). Neon is a noble gas, which are generally referred to as inactive non-metals because they have a full outer electron shell and do not readily participate in chemical reactions.
Helium would be the element that fits this description. It has a high ionization energy, meaning it requires a lot of energy to remove an electron, and tends to be chemically inactive because its outer electron shell is full.
A filled highest occupied principal energy level
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
Technetium is considered to be an active element because it typically forms compounds and undergoes chemical reactions. It is a silvery-gray metal that is radioactive and does not occur naturally in the Earth's crust, making it an artificially produced element in nuclear reactors.
Is nickel active or inactive
Fermium is a radioactive chemical element.
Neon (Ne) is a chemical element, natural, gas, practically inactive.
Bromine is an element that is not typically involved in the cycling of matter on Earth. It is considered to be a relatively inactive element in terms of biogeochemical cycles.
Helium has completely filled valence orbitals (and thus has stable electronic configuration). Hence is is chemically inert or inactive. In fact, helium doesn't react with any other element.
Francium is a very radioactive and very chemically reactive chemical element.
The element that means lazy in Greek is "Argon." This term originates from the Greek word "argos," which translates to "lazy" or "inactive." Argon is a noble gas with the atomic number 18 and is commonly used in various applications such as welding and lighting.
The element that fits this description is neon (Ne). Neon is a noble gas, which are generally referred to as inactive non-metals because they have a full outer electron shell and do not readily participate in chemical reactions.
Helium would be the element that fits this description. It has a high ionization energy, meaning it requires a lot of energy to remove an electron, and tends to be chemically inactive because its outer electron shell is full.

The Active topology functionally allow you to make element inactive (and chnage them back active again).
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
