Oxygen is chemically active because it reacts with other chemicals such as hydrogen to form water.
The literal meaning of inert is lacking the ability or strength to move. It can also refer to something that is not chemically reactive or chemically inactive.
Helium, neon, argon are used because they are chemically inactive.
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.
A chemically inactive substance used for comparison with active drugs in an experiment is called a placebo. Placebos do not contain any active ingredients but are given to participants as a control to measure the effects of the active drug. This helps researchers determine if the observed effects are due to the drug being tested or are the result of psychological factors.
When carbon and oxygen combine chemically, they form carbon dioxide (CO2), which is a colorless gas commonly found in the atmosphere. This process usually occurs during combustion or respiration.
argon
Bromine is chemically active. It is a halogen and readily forms compounds with other elements, making it reactive in chemical reactions.
Chemically joining phosphorus and oxygen creates phosphorus pentoxide (P4O10).
When oxygen is part of a compound or a mineral, it is chemically bound in that position. But it is otherwise chemically identical to the oxygen in the air.
The literal meaning of inert is lacking the ability or strength to move. It can also refer to something that is not chemically reactive or chemically inactive.
Francium is a very radioactive and very chemically reactive chemical element.
Copper and oxygen form copper(II) oxide (CuO) when chemically united.
Xenon is chemically inactive under STP. But under extreme conditions it reacts with more electronegative elements like fluorine and oxygen to from compounds like XeF2, XeOF4, XeF4, XeF6 etc.
Helium, neon, argon are used because they are chemically inactive.
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.
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.
it is inactive and cold blooded
