What else can I help you with?
How many many electrons are needed in the outer energy levels of most atoms for the atom to be chemically stable?
Generally speaking, it would be 8 electrons, but there are many exceptions.
How the number of electrons in an energy level affect bond formation?
If the atom is chemically stable it doesnt need to bond, it is chemically stable when the outermost level is completely full of electrons
How many electrons does a chemically stable atom have in its outer energy level?
8 electrons
Are the atom is chemically stable when its outer energy level contains all the electrons it can hold?
yes
Do metals and non metals become more chemically stable when they fill or empty their outermost energy levels?
When they fill their outermost energy levels. Metals will WANT more electrons and Non-Metals will have EXTRA electrons to give. So in a way, Metals will actually fill their outermost energy levels while Non-Metals will empty them; all with the goal of having a FULL valency shell which is stable. This is the basis for ionic bonding.
In covalent compounds atoms become chemically stable by doing what?
In covalent compounds, atoms become chemically stable by sharing electrons with each other to fill their outermost energy levels. By sharing electrons, atoms can achieve a full outer electron shell, which is typically 8 electrons for most elements (except for hydrogen and helium which need 2 electrons).
What makes the electrons more stable?
Electrons are more stable when they are in lower energy levels, closer to the nucleus of an atom. They are also more stable when they are paired with another electron in the same orbital, following the Pauli exclusion principle. Additionally, atoms are more stable when their outermost energy levels are filled with electrons, resulting in a full valence shell.
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
Why are noble gases considered chemically inactive?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Do electrons in stationary states emit the most radiation?
No, electrons in stationary states do not emit radiation because they are in stable energy levels. Radiation is emitted when electrons transition between energy levels, releasing photons of specific energies.
What is the group number for elements that have a stable number of electrons in their energy levels?
They r noble gases which have stable valance shell and grotp no. 18
What are noble gases and why are they chemically stable?
There are six noble gases: helium, neon, argon, krypton, xenon and radon. Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
