How many electrons does each atom desire?
Atoms do not actually have desires as such, although the metaphor can be useful. Atoms are more stable when they have a full outer electron shell. The smaller atoms, hydrogen, helium, lithium, and beryllium, can obtain a full outer shell with only two electrons in it. The heavier atoms require 8 electrons to have a full outer shell. That is known as the octet rule (an octet is a set of eight).
Is the outer shell of nickel full?
The outer shell of nickel is not full. Nickel has an electron configuration of 4s2 3d8, so its outer shell has two electrons which is not the maximum it can hold (which would be 8).
What is the most stable outer orbital arrangement of electrons after a chemical reaction?
The most stable outer orbital arrangement of electrons after a chemical reaction is typically achieved when the atom has a full outer shell of electrons, usually eight electrons (except for hydrogen and helium, which have a full outer shell with two electrons). This configuration is known as the octet rule and is associated with greater stability due to a lower energy state.
How many more valence electrons does oxygen need to have a full outer?
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
How many electrons in atom will make it inert?
An atom is considered inert when it has a full outer electron shell. For most atoms, this means having 8 electrons in the outer shell, except for hydrogen and helium which only need 2 electrons in their outer shell to be stable.
How many electrons are in hydrogen's outer level when it is full?
There would be two electrons. The electronic configuration would be just 1s2 and this is termed the duplet configuration.
Does helium have a complete outer shell?
Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell. Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.
How many electrons are in the outermost energy level of a oxygen atom as it shares electrons with hydrogen atoms as a part of a water molecule?
There are 6 electrons in the outermost energy level of an oxygen atom. In a water molecule, oxygen shares electrons with two hydrogen atoms to form covalent bonds, achieving a full outer shell with 8 electrons (octet rule). Oxygen shares one electron with each hydrogen atom to complete its outer shell.
Does calcium have a full outer shell?
Calcium has a full 4s sublevel, but does not have a full "outer shell", per se, because it is not a noble gas.
How many electrons fill the outer shell in hydrogen?
An energy level is the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. There are no full energy levels in an atom of hydrogen. The first energy level of any atom can hold 2 electrons. Hydrogen only has one electron and it is in the first energy level.
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 is considered a full outer ring of an atom?
A full outer ring of an atom is when it has achieved the stable electron configuration known as the octet rule, where the outermost energy level is filled with 8 electrons (2 electrons for hydrogen and helium). This makes the atom more stable and less reactive.
Would hydrogen and fluorine form an ionic bond?
Hydrogen and fluorine would not form an ionic bond. Instead, they would form a covalent bond due to their similar electronegativities. In a covalent bond, they share electrons to achieve a full outer electron shell.
What kind of bond is Hydrogen Sulfide?
Hydrogen sulfide is a covalent bond because it forms when two nonmetals share electrons to achieve a full outer shell.
Why do noble gases not normally form compounds?
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.
Why does does oxygen and hydrogen react together?
because they both want to gain full outer shell. They don't have completed outer shells. Hydrogen has one electron in it's outer shell so it wants to ger rid of that by giving it to oxygen. (oxygen itself needs two electrons to get full outer shell which is 8 electrons, so two hydrogens are needed to complete one oxygen atom) and then water is formed.
How many valence electrons are needed to achieve a full outer shell?
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
