Elements for Kids Argon is the most abundant of the noble gases in the Earth's atmosphere. It constitutes nearly 1% (0.94%) of the volume of air making it the third most abundant element in air after nitrogen and oxygen.Argon is also found in small traces in the Earth's crust and ocean waters.Argon is usually produced from liquid air as a byproduct of the production of nitrogen and oxygen.rgon has three isotopes that are stable including argon-36, 38, and 40. By far the majority (over 99%) of argon found naturally on Earth is argon-40. The most common argon isotope in the universe is created by stars and is argon-36.

What Does the Atomic Number of an Element Tell You? Krypton's atomic number is 36, which means that there are 36 protons in the nucleus of one atom of krypton. Krypton also has 36 electrons. Protons are positively charged, whereas electrons are negatively charged. In this way, an element cancels out the positive and negative charges to remain in an electrically neutral form.

Merlin's Questions Determine the number of electrons. Protons are particles in the nucleus of an atom that have a positive charge equal to +1. Electrons are particles that have a negative charge equal to -1. Therefore, an element in a neutral state will have the same number of protons and electrons. For example, boron (B) has an atomic number of 5, therefore it has 5 protons and 5 electrons. However, if the element includes a negative or positive ion, then the protons and electrons will not be the same. You will have to calculate them.

- Number of neutrons. However, not all nitrogen nuclei have 8 neutrons in a nucleus. They can have 5, 6, 7, 8, 9, 10 or 11 neutrons. We call these different isotopes of nitrogen. There are always 7 protons because the nucleus is always a nitrogen nucleus (Z=7).Since different isotopes of an element have different numbers of neutrons (but always the same number of protons) they have different mass numbers. The isotopes of nitrogen have mass numbers ranging from 12 to 18.We call them nitrogen-12, nitrogen-13, nitrogen-14 and so on. Some isotopes of nitrogen are unstable.here are always 7 protons because the nucleus is always a nitrogen nucleus (Z=7). Since different isotopes of an element have different numbers of neutrons (but always the same number of protons) they have different mass numbers.

- Argon is the third most common gas in the Earth's atmosphere, at 0.93% (9,300 ppm), making it approximately 23.7 times as abundant as the next most common atmospheric gas, carbon dioxide (390 ppm), and more than 500 times as abundant as the next most common noble gas, neon (18 ppm).lthough argon is a noble gas, it has been found to have the capability of forming some compounds. For example, the creation of argon fluorohydride (HArF), a compound of argon with fluorine and hydrogen which is stable below 17 K, was reported by researchers at the University of Helsinki in 2000.

How Many Protons, Neutrons and Electrons Does Potassium Have? An element's atomic number is the same as the number of protons in the element. Because potassium has an atomic number of 19, it has 19 protons. A neutral atom has the same number of protons and electrons, so one neutral atom of potassium must also have 19 electrons. The number of neutrons in an element is equal to the element's mass number minus the number of protons in one atom of the element, according to the Thomas Jefferson National Accelerator Facility Office of Science Education.

- The existing atmosphere surrounding the earth contains a little less than one percent of the inert gas Argon, an approximate total of 6.59 x 1019 grams. The isotope Argon-40 (40AR) is 99.6 percent of the total Argon. The only know source of 40Ar is the radioactive decay of Potassium-40 (40K), of which 11.2 percent decays into 40AR and the remainder into Calcium-40 (40CA).

ARGON It was the first of the noble gases to be isolated. Rayleigh and Ramsay discovered argon by the fractional distillation of liquid air. Fractional distillation is the process of letting liquid air slowly warm up. As the air warms, different elements change from a liquid back to a gas. The portion of air that changes back to a gas at -185.86°C (-302.55°F) is argon.

What Does the Atomic Number of an Element Tell You? Krypton has a mass number of 84. The mass number is the sum of the number of protons and neutrons present in the nucleus of an atom. By subtracting 36 protons from the mass number of 84, it is determined that krypton has 48 neutrons. Atoms may gain or lose neutrons, and these different forms of the element are known as isotopes.

Facts About Argon 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.n Earth, the vast majority of argon is the isotope argon-40, which arises from the radioactive decay of potassium-40, according to Chemicool. But in space, argon is made in stars, when a two hydrogen nuclei, or alpha-particles, fuse with silicon-32. The result is the isotope argon-36.

How many protons and electrons are in an atom of sodium with an atomic number of eleven? An element's atomic number indicates the number of protons it has in the nucleus. In this case, since polonium's atomic number is 84, it has 84 protons. In a neutral atom, t … he number of protons is the same as electrons. This is because the positive charge of the protons in the nucleus must be balanced with by the negative charge of the electrons.
