idk if this is right...but a element with a positive ion (Cation) will combine with a element with a negative charged ion (Anion) to fill the outermoast level so the outermost energy level is filled. (For Cations its easyer to give a electron then tacke because they have less vallance electrons)

The atom must gain or lose just the right amount of energy. The higher an electron is on the energy ladder, the farther it is from the nucleus.
in order for an electron to move from one energy level to another it must be quantized.
electrons fill energy levels by what size the level can hold, the starting level is level K it can hold two electrons and then the electrons increase in size the farther away from the nucleus it becomes.
When a bond forms between two hydrogens and one oxygen to form a water molecule, a sharing of electrons occurs between the hydrogens and oxygen. This sharing fills the energy level in each of the hydrogen atoms.
In order for an electron to from a lower energy level to a higher one, it needs the input of energy. The opposite is true for an electron going from a higher energy level to a lower one. In this case, energy is emitted as it falls to a more stable position.
umm. I think I know what you are asking. Well, in the first level ther can be 2 electrons, in the second and third level each can hold 8 electrons.
2+8+8 = 18 electrons!
Sorry if this doesn't help. Your question is quite confusing.
1s fills with 2 electrons (e-)
2s fills next with 2 e-
2p fills next with 6 e-
3s fills next with 2 e-
3p fills next with 6 e-
The 4s then fill with 2 e-
The 3d fills after that with 10 e-
d is the last sublevel of the 3rd energy level, but it does not fill until the 4s sublevel gets 2 e-
electrons?
No, the tendency is to fill out lower energy levels first.
these principle energy levels are satisfied first
The Aufbau principle states that electrons will fill up the different orbitals in an atom in order, i.e. the s orbitals of an atom will be filled by electrons before the p orbitals.
Halogens have 5 electrons in their outermost p shell in their electrically balanced state. The p shell has 3 orbitals in each energy level. Halogens have 2 filled orbitals each with 2 electrons in them and one orbital with only one electron in it. In order to obtain the stable noble gas electron configuration, halogens gain one electron to completely fill the p shell on the outermost energy level. This gives halogens a charge of -1.
lone pair of electrons & bonded pairs of electrons
Electrons fill orbitals in order of increasing orbital energy. The exact order of these energy levels is shown at the related link below.
No, you are misinformed, it is electrons not gasses that fill energy levels.
No, according to Hund's rule the electrons fill the lowest orbital first and foremost and then go on to fill higher orbitals.
1st energy levels only in which hydrogen will have only one electron whereas helium will have two electrons.
Covalent Bonds. :)
no!
The principle is: electrons fill first the lower energy levels.
The answer which I found turns out to be energy level
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
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.
Hydrogen and Helium both only need two valence electrons to fill their outer shell.
A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.
