A neutral atom is one that has an equal number of protons and electrons. The positive charge of the protons and the negative charge of the electrons will cancel each other out. In the case of argon, it has 18 protons and thus will be neutral if it has 18 electrons in total between al...
Electron/shells/valence, Protons In an atom of argon there is a total of 3 electron shells 8 with 8 valence electrons and 18 electrons, which is the same as its protons and atomic number. With an overall atomic mass of 39.948 or 40. Period, Group and Formula Argon is the third of the...

While the number of protons must stay the same to qualify as a particular element, there is no restriction on the number of neutrons that can be found in a nucleus. The different isotopes are identified by their mass number, the total of their protons and neutrons.Answer and Explanation: Th...
The proportions in which atoms of elements combined to form ionic or covalent compounds (their “valences”) were thus controlled by the behaviour of their outermost electrons, which—for this reason—were called valence electrons. This theory explained the chemical bonding of the reactive elements,...
This energy range covers the predicted location of the Cooper minimum of the neutral as well as the singly charged argon24. Aiming to increase the total FEL pulse energy to a level that allows for efficient data collection, for most of the reported data, the FEL was operated in a special ...
- Mass Number: The total number of protons and neutrons in the nucleus of an atom. Step 2: Identify the Atomic Numbers- The atomic number of calcium (Ca) is 20.- The atomic number of argon (Ar) is 18. Step 3: Identify the Mass Numbers- The mass number of both calcium and argon ...
Select the correct answer. Which of the following elements makes up the majority of Earth's atmosphere? a. Oxygen b. Hydrogen c. Argon d. Nitrogen Elements in the atmosphere Although the Earth's atmosphere contains a lot of ...
The molar mass of an element is defined as the mass of one mole of that substance. Answer and Explanation:1 False. One mole of any element contains the same number of atoms. This number of atoms is known as Avogadro's number. Its... ...
