What is the value of the nuclear charge on a neon atom?
The nuclear charge of an atom is the total charge of all protons in the nucleus. This is the same as the atomic number so for a neon atom it is 10.
While a sodium ion and neon atom both have 10 electrons they are of different elements as a neon atom has 10 protons while sodium has 11. As a result the neon atom is neutral while the sodium ion carries a positive charge. So neon can exist on its own as a gas while sodium ion needs a negative ion to balance its charge and form an ionic solid.
Does the sodium ion and the neon atom have the some atomic number number of electrons number of charge?
A sodium ion would have a charge on it, such as a positive charge, a cation, or a negative charge, an anion. Take your charge to be Na+1. This means that sodium is missing one electron, thus having one more proton giving it a positive charge. Na normally has 11 electrons, but this plus one knocks it down to 10. Neon at a neutral charge has 10 electrons. So, a sodium ion and neon atom…
There is a neutral charge on an atom when the number of protons is equal to the number of electrons. This is most common in the Noble gases, such as Neon (atomic number 10, the second Noble Gas), where there are 10 protons and 10 electrons, with the negative charge on the electrons balancing out the positive charge of the protons exactly.
What happens to an atom of magnesium (Mg) when it forms an ionic bond in which it has the same electron configuration as the noble gas neon?
What happens to an atom of fluorine when it forms an ionic bond in which it has the same electron configuration as neon?
Trick question. Ion implies charged atom. Each proton gives a +1 charge and each electron gives a -1 charge. Thus, 10 protons (Neon, fyi) with 10 electrons has a net charge of 0. Isotope (maybe the term you're looking for?) is an atom with more or less neutrons than normal (usually as many as protons).
Sodium and magnesium form positive ions because they lose electrons in order to have a filled valence shell, like a noble gas. A sodium atom loses one electron so that its ion has a 1+ charge and the noble gas configuration of neon. A magnesium atom loses two electrons so that its ion has a charge of 2+ and the noble gas configuration of neon.
An atom of an element for example Neon (Ne) is neutral (no positive or negative charge as it has 8 electrons in the outer shell) and is very stable. It is a noble gas because the outer electron shell is filled which makes it largely chemically inert, and it is stable because it's usual isotope does not undergo nuclear decay. Most of the 92 naturally occurring elements, in their most abundant isotope, are stable.
An atom is composed of two parts (in the Rutherford model), the nucleus and the electron shells. The nucleus contains Neutrons and Protons. The electron shells contain Electrons. The protons are positively charged. The neutrons have no charge. The electrons have a negative charge. (The names negative and positive are traditional.) A complete atom is normally balanced, it will have an equal number pf protons and electrons. If an electron is knocked off, the atom…
The mass of an atom is determined by the number of protons and neutrons, which each have a mass, by definition, of 1 AMU. The mass of the electrons in the surrounding cloud doesn't add enough to change the value within a reasonable number of decimal places. Since the nuclear particles have a mas value of 1.0000..., the mass of a single atom has no decimal places. The decimal place values on the Periodic Table…
