Will an atom that has 3 electrons in its second shell and a filled first shell gain 5 electrons in its second shell?

No not if you mean gain to become a 5- anion. Possibly if you mean share 5 to become a covalent molecule.
This is really a discussion about boron. There are a number of choices for boron, lose 3 to become B3+ , gain 5 to become B5-, share electrons to achieve the octet.
B3+ and covalency look the best options. B3+ does not exist-- reasons the sum of the first 3 ionization potentials for B is high 6900kJ/mol (compared to Al with about 5000 kj/mol), B3+ if formed it would be really small and polarising- and an ionic bond would be impossible. Covalency is a good option, B will form 3 covalent bonds say with a chlorine or hydrogen and then needs an extra 2 say from a ligand with a lone pair such as Cl-, or H- to form tetrahedral anions

How many unfilled electron positions are in a carbon atom?
Carbon has an atomic number of 6, therefore the first valence shell is filled with two of the electrons, leaving four electrons and eight empty spaces on the second valence shell. So... 4 XD Hope this helped
Inner-shell electrons are electrons that?
inner shell electrons : the electrons that are not in the the highest occupied energy level .
What electrons are the outer most shell of electrons in a atom?
Valence Electrons
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.
There are four electrons in every electron shell?
No, on the most inner shell, only 2 electrons can be held, but then on every other shell it is usally 8
An atom that has 3 electrons in its second shell and a filled first shell will?
lose 3 electrons from its second shell
What level is filled by krypton?
The fourth electron shell is filled by krypton. Krypton is the last element in the fourth period on the periodic table. Each of the periods represents an electron shell. Elements in the first period have electrons in the first shell; elements in the second period have electrons in the second shell; and so on.
How many electrons are there in a first shell of a neutral neon atom?
Neon atom number 10: first shell (K) : 2 electrons second shell (L): 8 electrons all shells being filled up completely
How many electrons go in the first shell of oxygen?
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
How many electrons are in the valence shell of He?
There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.
How many electrons can the second shell of an atom hold?
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
You have two completely filled shells and no electrons anywhere else?
IF you have 2 complete full shells and no electrons any were else that means you have 2 electrons in the first shell and 8 electrons in the second shell which is 10 electrons in other words it is neon
What is the configuration of an atom with 31 electrons?
the first shell: 2 electrons The second shell: 8 electrons The third shell: 18 electrons The fourth shell: 3 electrons
How many electrons do silicon atoms have?
14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
What are the maximum number of electrons found in the first shell and second shell?
First orbital can be occupied by a total of 2 electrons and the second orbital can be occupied by a total of 8 electrons. 1s^2 2s^2 2p^6 ( what element is this ? )
