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 (:

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 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 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 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 does the atoms electrons in their outer shells does the Octet Rule state they need?
8 electrons and yes, the Octet rule states this
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 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.

So the water molecule is self contained, it does not need any more electrons.
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 octets of electrons are in a Lewis structure?
The maximum number of electrons in a Lewis structure is eight, which is an octet of 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 many electron must phosphorus gain in order to achieve an octet?
This atom must gain 3 electrons to achieve an octet.
How many electrons does fluorine need to satisfy the octet rule?
One
