What is an ion and what happens to electrons when ions are formed?
An ion is an atom with a net electric charge. An ion is formed when an atom either gains or loses a valence electron. Atoms with an unfilled outer shell tend to gain or lose electrons so they can achieve a filled outer shell. Atoms that gain an electron are negative ions, and atoms that lose an electron are positive ions.
What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
Are the outer electron shells always filled first?
No. The inner shells are filled first.
What is the electron called when the electrons in the outer shell of atoms?
These are the valence electrons.
Why are noble gases chemically inactive?
The noble gasses all have a filled outer electron shell of eight electrons, except helium which has two electrons. Since their outer electron shells are filled, they are less likely to react with other atoms.
Are atoms with eight electrons in the outer shell not reactive at all?
stable and chemically nonreactive, or inert.
When a compound is formed by 2 or more atoms of different elements the outer electron shell of the compound is completely filled with electrons?
This answer is True!

When a compound is formed by two or more atoms of different elements joining the outer electron shell of the compound is completely filled with electrons?
true
When a compound is formed by two or more atoms or different elements joining the outer electron shell of the compound is completely filled with electrons?
yes
Why can an atom lose electrons easily?
Atoms do not always lose electrons. Electrons can be gained too. Atoms always try to have their outer most shell filled, and some atoms such as ones of potassium can easily lose an electron rather than gain an electron. So it would lose an electron to a different atom so that it would have a full outer shell and the other atom would also have a full outer shell.
When a compound is joined by two or more atoms of different element joining the outer electron the compound is filled with electrons?
When a compound is formed from two or more atoms of different elements, the chemical bonds that form cause the atoms in the compound to have filled valence shells.
What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
What is more stable partially filled or full electron shells?
Atoms with full outer electron shells are more stable. The atoms (elements) with full outer electron shells are the noble (sometimes called inert) gases. These are the elements in Group 18 of the periodic table, and you know them as helium, neon, argon, krypton, exnon and radon.
Why does a atom with a filled outer energy level of electrons not react well?
Because it's in a stable state. Atoms with an electron 'missing' from their outer shell will always try to 'grab' one back to stabilize themselves. This is often done by combining with other atoms and 'sharing' an electron in order to reach stability.
What is the name of an atoms outer region?
electron cloud
Is it true or false when a compound is formed by two or more atoms of different elements joining the outer electron shell of the compound is completely filled with electrons.?
true
