When is an element stable?
For an element to be stable, it must have a full outer shell (valence shell) of electrons. An element with a full outer shell of electrons will act like its nearest noble gas and be stable. Most elements require 8 valence electrons to be stable, however H needs 2.
What element has a stable 2 valence electrons?
Calcium.
How many electrons are needed in the outer energy levels of most atoms for the atom to chemically stable?
All
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
What is the primary characteristic of an element that makes it a good insulator?
If the the number of electrons on the shell are stable.
How many electrons does each element need to be stable on its outside level?
eight
How does an atom of a representative element achieve its most stable state?
The valence shell must be completed to eight electrons.
When an element has the same number of protons and electrons the element is a?
the element is stable.
When is an element stable?
For an element to be stable, it must have a full outer shell (valence shell) of electrons. An element with a full outer shell of electrons will act like its nearest noble gas and be stable. Most elements require 8 valence electrons to be stable, however H needs 2.
Is the krypton element stable or unstable?
no it is not stable bcoz if an atom needs to be stable it needs to have 8 electrons in the valency (outermost) shell,where as a krypton has only 2 in its valency electron.
What family of element is relatively unreactive and why?
Nobel gases are relatively nonreactive because they have eight electrons in the outermost energy level, which is a stable configuration
What element is stable with 2 valence electrons?
calcium
What element has a stable 2 valence electrons?
Calcium.
How many electrons must beryllium loose to become stable?
Beryllium is a stable element.
What makes an element stable?
an element is stable when it has a full outer shell of electrons. to abide by the octet rule it must have a shell of 2 then 8 electrons. An element with a full outer shell (8) will be stable and act like its nearest noble gas.
Is titanium indestructible?
Titanium is an element that has 5 naturally occurring isotopes.
What element has eight electrons?
Oxygen.
