An octet is 8 electrons- but even 2 electrons are okay for achieving stability.
A beryllium atom has 2 shells, with 2 electrons in each shell. Since it is a metal, it will lose electrons instead of gaining them, forming a positively charged ion.
This means that it will lose both the electrons in its outermost shell, leaving it with a single shell containing 2 electrons.
So, basically beryllium loses 2 to electrons to form a stable duet with a charge of 2+!
Hope this helped you (:
What else can I help you with?
How many electrons must an atom have to fulfill the octet?
2 or more electrons, because Oxygen already has 8.
Is water an exception to the octet rule?
It is one of many, many exceptions to the octet rule. Hydrogen does NOT require 8 electrons.
How many electron must phosphorus gain in order to achieve an octet?
This atom must gain 3 electrons to achieve an octet.
What The octet rule is satisfied when two atoms acquire how many valence electrons?
Eight
How many electron are required for water to complete its octet structure?
Water is a molecule made of three atoms (one oxygen and two hydrogen) and the concept of the electron octet applies to atoms, not to molecules. Oxygen, with six valance electrons, can acquire an octet by sharing the electrons of two hydrogen atoms, each of which have one electron. So the water molecule is self contained, it does not need any more electrons.
How many electrons does oxygen need to reach an octet?
Oxygen needs to gain 2 electrons to reach an octet, as it has 6 valence electrons in its outer shell and requires a total of 8 electrons to have a stable octet configuration.
How many electrons must an atom have to fulfill the octet?
2 or more electrons, because Oxygen already has 8.
If an element has an octet of electrons in its highest energy level there are how many electrons in this level?
8: that's the meaning of "octet".
How many Valence electrons in a stable octet?
8 valence electrons
How many more electrons does Fluorine need to have a stable octet?
Fluorine needs one more electron to have a stable octet, as it has 7 valence electrons and stable octet configuration is achieved with 8 electrons.
Is water an exception to the octet rule?
It is one of many, many exceptions to the octet rule. Hydrogen does NOT require 8 electrons.
How many more electrons does silicon need in order to have a stable octet?
Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.
How does the octet rule help you determine the oxidation number of an element?
The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons. By following this rule, you can determine the oxidation number of an element based on how many electrons it gains or loses in order to reach a full octet. The oxidation number corresponds to the charge an atom would have if the compound were ionic.
How many electrons are in a complete octet why is having a complete octet important?
eight. it is important to obtain octet so that elements become stable.
How many electrons does an atom of oxygen need in order to complete it's outermost energy level?
An atom of oxygen needs to gain 2 electrons in order to complete its outermost energy level and achieve a stable octet configuration. Oxygen has 6 electrons in its outer shell and it can reach a total of 8 electrons, following the octet rule.
What is significant of octet rule?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
How many electron must phosphorus gain in order to achieve an octet?
This atom must gain 3 electrons to achieve an octet.
