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...
An ionic bond is formed when electrons are transferred while a covalent bond is formed when the electrons are shared between the atoms. Both types of bonds involves the present of valence electrons. Valence electrons are the electrons present in the outer ...
regime have predicted a significant influence of the magnetic field component on population mixing between excited states that is strictly forbidden in the dipole approximation18. The discussed Raman-type two-photon transition could have a strong, pulse duration-dependent influence on the total cross ...
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 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... ...
