What is an element that needs three electrons to become stable?
An element that needs three electrons to become stable is nitrogen. Nitrogen has five valence electrons and can gain three more electrons to achieve a full outer shell of eight electrons, making it stable.
What element has a stable 2 valence electrons?
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
How many valence electrons will make an element happy or stable?
Most elements are stable with a full outer shell of electrons, typically with 8 electrons known as the octet rule. However, elements in the first shell can be stable with 2 electrons. This full outer shell results in a stable configuration similar to the noble gases, making the element happy or 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.
How many electrons are needed in the outer energy levels of most atoms for the atom to chemically stable?
All
How many electrons does each element need to be stable on its outside level?
eight
What is an element that needs three electrons to become stable?
An element that needs three electrons to become stable is nitrogen. Nitrogen has five valence electrons and can gain three more electrons to achieve a full outer shell of eight electrons, making it stable.
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.
What element has a stable 2 valence electrons?
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
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
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 element has eight electrons?
Oxygen.
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.
What is one way an element can achieve a stable electron configuration?
An element can achieve a stable electron configuration by either gaining, losing, or sharing electrons to attain a full outer electron shell, usually with eight electrons, known as the octet rule. This helps the element to have a stable configuration similar to the nearest noble gas, making it more energetically favorable.
How many valence electrons will make an element happy or stable?
Most elements are stable with a full outer shell of electrons, typically with 8 electrons known as the octet rule. However, elements in the first shell can be stable with 2 electrons. This full outer shell results in a stable configuration similar to the noble gases, making the element happy or stable.
