filled with electrons

∙ 11y agoIt is true of the hydrogen atom, that if it loses the one electron that it has, and as a result its outermost and only shell is empty, that is a stable state, and hydrogen typically does undergo chemical reactions which leave it with no electrons, although it also undergoes chemical reactions in which it winds up with a full outer shell of two electrons. All the metals tend to lose electrons when they undergo chemical reactions, and they are all stable when they have lost all of the electrons in their outer shell.
Non metals are different. If an element has lots of electrons in its outer shell, such as oxygen which has six electrons in its outer shell, and you take away all of those electrons, you are left with a very strongly charged ion, having a charge of +6. With such a strong charge, it will have a powerful attraction for electrons. This is quite different from the hydrogen atom. When it loses one electron, it has a charge of +1. And if there is a very strong attraction for electrons, that is not a stable state. Electrons are going to be attracted, and captured by that ion, under normal circumstances (although at a sufficiently high temperature, all atoms lose their electrons).

∙ 12y agoNo, a atom is chemically stable when it outer shell are full.

∙ 9y agoIt depends on what level its valence electrons are in. It could be 2, 8, 18, 32, 50, or 72. If its outer energy level is not filled, the atom is unstable.

∙ 15y agoIt is. An element will try to combine with other elements that will complete an outer shell to provide stability.

How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
How many electrons would be filled by a neutral xenon atom?
A xenon atom contains 54 electrons,
What is the neutral atom that has its first two energy levels filled has 1 electrons in its third energy level and has no other electrons?
Sodium
What element contains a full second energy level?
I think it will be zinc. The electron configuration of zinc is: 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10 Add up the electrons. 2+2+6+2+6+2+10 = 30 electrons in all, which is the element zinc. As you can see frorm the above electron configuration, all the electrons for the third energy level are filled: 3s2 is filled; 3p6 is fully filled; 3d10 is fully filled. I really hope this helps and doesn't confuse you... :)
Are atoms with eight electrons in the outer shell not reactive at all?
stable and chemically nonreactive, or inert.
An atom is chemically stable when it’s outer ____ is completely filled with?
Its outer shell is filled with electrons.
How are the electrons arranged in energy levels?
The innermost energy level always contains two electrons and the rest are arranged in 8s. for example the energy levels of calcium- 2,8,8,2. calcium contains 20 electrons. once the energy levels are filled upto 8 electrons then we move from onto the next energy level. hope this makes sense lol :)
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.
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled?
the one that is completely filled
How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs 2 valence electrons to have a filled outermost energy level.
What is a chemical property of helium?
Helium has completely filled orbitals / energy levels and is chemically inert. So it has no chemically property.
Does neon comnbine with other elements?
No neon doesn't as it has completely filled valence electrons and is chemically inert.
If the outermost electron shell of an element is not filled with electrons to its maxium capacity the element is not chemically active?
