Why is argon mass 40?
1 Answer. Stefan V. Because argon has three stable isotopes that contribute to the element’s atomic mass.
How do you find the mass number?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What is the mass number of argon 40?
What does the 40 in Argon-40 mean?
Wiktionary. argon-40(Noun) The major stable isotope of argon, , having eighteen protons and twenty-two neutrons; it amounts to about 99.6% of the element in nature.
Is Argon-40 Stable?
Argon (Ar) has three natural isotopes with masses 36, 38, and 40. Ar and 38Ar are stable, that is, they are not radioactive, and they are also not produced by radioactivity processes. Argon-40 is not radioactive but is produced by the decay of 40K, a rare isotope of potassium.
What is the normal phase of argon?
Why is argon called the lazy one?
Argon is an inert, colorless and odorless element — one of the Noble gases. Used in fluorescent lights and in welding, this element gets its name from the Greek word for “lazy,” an homage to how little it reacts to form compounds.
What does argon look like?
Argon is a colourless, odourless gas that is totally inert to other substances. Argon is often used when an inert atmosphere is needed. Argon is used in fluorescent tubes and low-energy light bulbs. A low-energy light bulb often contains argon gas and mercury.
Can argon kill you?
Argon can kill you if it replaces too much air and therefore decreases the partial pressure of oxygen too much. Argon can also kill you if you directly inject it into your bloodstream, causing a gas embolism.
How dangerous is Argon?
Argon is nontoxic and largely inert. It can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life. Inhalation of argon in excessive amounts can cause dizziness, nausea, vomiting, loss of consciousness, and death.
How do we use argon everyday?
Everyday Uses of Argon Gas
- Air Source Industries offers different grades of argon gases for commercial, industrial, and ultra-high purity purposes in the greater Los Angeles and Orange County areas.
- Electrical Light Bulbs.

Where do we find argon in everyday life?
Because it is inert, you will find argon in light bulbs, welding, and vacuum tubes (although you probably don’t know what those are). Once isolated, argon was not that special. It has no smell and no color. It wound up as the last element in period three at position number eighteen.
Does argon have a full outer shell?
Although argon does not technically have a full outer shell, since the 3n shell can hold up to eighteen electrons, it is stable like neon and helium because it has eight electrons in the 3n shell and thus satisfies the octet rule.
Is argon a lustrous?
2) Six of the nonmetals like carbon , boron , phosphorous , sulphur, selenium and iodine are solid. Bromine is the only liquid nonmetal at room temperature. Other nonmetals are gases like oxygen, nitrogen, fluorine , chlorine, hydrogen, helium, argon , neon, krypton, xenon, radon . 3) They are non-lustrous.
