What is the highest occupied energy level of Beryllium?
2s2
Ion electron configuration for beryllium?
Group 2 = 2 valance electons. Row 2 = Second energy level. = 1s2, 2s2. Confirm this with Beryllium being the fourth element and having four electrons - check.
An unknown element in group 2 has a total number of 12 electrons and two electrons in its outer level. what is it?
beryllium
What is the energy level farthest away from the nucleus of the atom that holds 8 or more valence electrons?
The valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding. The electrons more loosely held by the nucleus - are the ones that are gained, lost or shared.
What is the word for the definition electrons in the outermost energy level of an atom?
valence electrons are the electrons in the outermost energy level
How many electrons do beryllium and magnesium have in there outer energy levels?
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
Which atom does not need 8 electrons in it outer energy level to be stable?
hydrogen, helium, lithium, and beryllium
Identify the element whose electrically neutral atom has 2 energy levels with 2 electrons in the outer energy level?
beryllium
What are valances?
They are electrons in the outermost energy level of an atom. They are the electrons that are either shared, lost, or gained in the proccess of forming chemical compounds
Which two atoms will have their outer energy level filled with 2 electrons?
There are more than two such atoms. Perhaps there was a list of atoms you had to chose from. Anyway, two such atoms are beryllium and magnesium.
What is an alkaline earth metal with 2 electrons in the 2nd level?
beryllium (Be)

How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
An unknown element in group 2 has a total number of 12 electrons and two electrons in its outer level. what is it?
beryllium
What is the highest occupied energy level in the element Beryllium?
2s
