A shell
What is The outermost ring of electrons in an atom?
"Electron cloud" is the name given to the electrons which surrounds the atomic nucleus.
How many electrons would you need to fill the outermost ring of hydrogen?
The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 electrons.
What term is used for the electrons in the outermost shell?
there called valence electrons
What does chemical reactivity have to do with electron configurations and energy levels?
The electronic configuration of an element gives an idea about its reactivity. The elements having a completely filled outermost orbit (or shell) will be chemically inert (non-reactive). For example, the outermost shell in the case of helium (He), neon (Ne) and argon (Ar) are completely filled as shown below. As a result, helium, neon, and argon are chemically inactive (or inert). These elements do not form compounds with other elements. Because of this chemical inactivity, these gases are called as noble gases (earlier these were called inert gases). The elements containing only one or seven electrons in their outermost shell show greater chemical reactivity, i.e., such elements react very fast with other elements. For examples, sodium and chlorine having the follows electronic configurations are highly reactive. Sodium 2, 8, 1 ---- Here, the outermost shell has been one one electron: one more than the completely filled shell. Chlorine 2, 8, 7 ----- Here, the outermost shell has seven electrons: one less than that required to fill the shell completely.
What is a ring-shaped shell of gas around a star called?
Planetary Nebula

"Electron cloud" is the name given to the electrons which surrounds the atomic nucleus.
What happens to an atom when it looses an electron?
If an atom loses an electron, its charge becomes a positive. (The process of losing an electron is called OXIDATION, by the way.) Depending on the electron configuration, the atom could become "happy" (because its outer ring is now empty) or it could want to bond with another atom to fill ALL of the spots on its outer electron ring.
What does the Shell model look like for Potassium Chloride?
A shell model is an electron configuration. The shell model for Potassium has two electrons on the first ring, eight on the second ring, eight on the third ring, and one on the fourth ring.
How many electrons would you need to fill the outermost ring of hydrogen?
The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 electrons.
When is an atom most stable?
Answer When the outermost shell(valence shell) is filled the atom is to be most stable. First Shell: holds up to 2 electrons Second Shell: holds up to 8 electrons Third Shell: holds up to 18 electrons Fourth Shell: holds up to 32 electrons

Why is the ring model of atomic structure useful?
It shows the electron shell and charges on the subatomic particles.
What is an atom shell?
electron shells are like the orbits of electrons around the protons and neutrons the atoms can have 1-3 shells
What does a atom's outermost electron shell does?
The outer energy level is in the electron cloud surrounding the nucleus. Each ring that surrounds the nucleus is an energy level and contains a different number of electrons.
Why elements in the same group have similar properties?
Take a look at the shells, each has a certain number electrons orbiting the central nucleus, in the case of the Nobel Gases, they all have 8 electrons except of course for hydrogen which has 2. Each ring has a certain number of electrons which causes the atom to be more stable than others. The outermost is called a valence electron shell. In the case of the Nobel Gases it causes the element not to be as reactive to other substances. Depending upon how many electrons are in the outer shell, will denote how reactive an atom will be. Those atoms with only 1 electron, will be quite non reactive where as those that are missing just one electron from making it complete will be quite reactive. They have the same outer electron structure.
