Electronic configuration of beryllium: 1s2.2s2.
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.

The electron configuration for the beryllium ion (Be^2+) is 1s^2 2s^2. Beryllium typically has an electron configuration of 1s^2 2s^2, but when it loses two electrons to become the Be^2+ ion, it loses the two outermost 2s electrons.
Yes, the electron arrangement in a sodium ion (Na+) is similar to neon. Both ions have a stable electron configuration with a full outer energy level (valence shell), making them inert and unreactive. Sodium loses one electron to achieve the same electron configuration as neon.
In most cases, yes beryllium has 4 protons and 4 electron, but this is only beryllium in neutral form. There is also an ion of beryllium though which has 4 protons and 2 electrons.

it is 2,8,8
no they have to be in the same group
2.8 There's a slight confusion if it is 2.8.3. well you see that is the electron arrangement of aluminium ATOM not ion. Hope this helps!
Na+ and neon are isoelectronic.
Lithium ion (Li+) and beryllium ion (Be2+) have the same electron configuration as helium because they both have filled electron shells.
An ion of bromine has the electron shell arrangement of 2, 8, 18, 7. Therefore, an atom that has the same electron shell arrangement would be one that has 35 electrons, such as the element bromine itself before it becomes an ion with a charge of -1.

A chlorine ion with a stable arrangement of eight valence electrons is called a chloride ion (Cl-). It achieves this stable arrangement by gaining one electron from another atom to fill its outermost electron shell.
The electron configuration for the beryllium ion (Be^2+) is 1s^2 2s^2. Beryllium typically has an electron configuration of 1s^2 2s^2, but when it loses two electrons to become the Be^2+ ion, it loses the two outermost 2s electrons.
Beryllium cation, or Be2+, is a positively charged ion of beryllium that has lost two electrons. Beryllium anion, or Be2-, is a negatively charged ion of beryllium that has gained two electrons. Both ions are formed to achieve a stable electron configuration by either losing or gaining electrons.
