How many valence electrons will beryllium gain or lose to fill its outer shell?
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
What are beryllium shell number?
Beryllium has two electron shells.
How can you tell that the beryllium atom is unstable?
You can tell that the beryllium atom is unstable because beryllium only has 2 valence electrons in its outer shell. An atom becomes stable when it has eight valence electrons, so in the case of beryllium it would have to lose those 2 electrons in its outer shell to become stable. often forming a cation with a 2+ charge.
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
What is the atomic number of helium's outer shell?
The outer shell of helium does not have an atomic number, that number belongs to helium itself whose atomic number is 2.
How many outer shells does beryllium have?
Beryllium has one outer electron shell with two electrons.
How many valence electrons will beryllium gain or lose to fill its outer shell?
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
What is the number of electrons of Be?
The number of electrons in the element Be (Beryllium) are 4. 2 in the first shell and 2 in the outer shell.hope I helped
What would be the charge of a beryllium atom that has a full outer shell?
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2
What are beryllium shell number?
Beryllium has two electron shells.
How can you tell that the beryllium atom is unstable?
You can tell that the beryllium atom is unstable because beryllium only has 2 valence electrons in its outer shell.

The melting point of beryllium is 1287 C while that of lithium is 180 C what is the large difference in the values?
It has to do with the number of electrons in the outer shell. Lithium, a group I element, has only 1 electron in its outer shell, and only delocalizes one electron in the metallic lattice (the solid form). Beryllium, a group II element, has 2 electrons in its outer shell, and delocalizes two electrons in the metallic lattice, which increases the attraction between the delocalized electrons and the metal ions.
What element begins with be?
The element with the chemical symbol Be is Beryllium. Beryllium is in Group 2 of the Periodic Table and, so, is an Alkaline Earth Metal. It has 2 electron shells, with 2 electrons in the outer shell and 2 in the inner shell.
What is the atomic number of hydrogen and the number of its electrons in the outer shell?
The atomic number for hydrogen (H) is 1, and it has 1 electron in the outer shell.
What is the atomic number of helium's outer shell?
The outer shell of helium does not have an atomic number, that number belongs to helium itself whose atomic number is 2.
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
How many outer orbital electrons is found in an atom of Be?
Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
