I'm guessing this means why only eight electrons. An atoms outermost orbit of electrons is called its valence. An atoms valence determines how reactive an element can be. There can actually be a lot more than 8 electrons in an atoms valence. There are 4 types of orbitals s,p,d,f. They contain 1,3,5, and 7 orbitals respectively. Each orbital can hold 2 electrons. There is specific sequence of electron filling order to know where they are placed in the orbitals. That's another story.
One trend that all noble gases have is that all the orbitals in their valence are filled. They are the most stable formations on the Periodic Table making them very unreactive. This question is unclear
What else can I help you with?
An atom is stable when its outermost orbit is?
An atom is stable when its outermost orbit, or valence shell, is complete with the maximum number of electrons it can hold according to the octet rule. This typically means having eight electrons for most elements, except for hydrogen and helium which only need two electrons in their outer shell to be stable.
How many electrons does calcium need to get eight valence electrons?
Calcium has two valence electrons in its outer shell. To achieve a stable octet configuration of eight valence electrons, it needs to lose these two electrons rather than gain any. Therefore, calcium does not need to gain any electrons; instead, it will typically lose two to achieve stability.
How many electrons does an atom need in its outer shell to be most stable and unreactive?
An atom is most stable and unreactive when it has eight electrons in its outer shell, a configuration known as the octet rule. This is because having a full outer shell typically leads to lower energy and greater stability. However, helium is an exception, as it is stable with just two electrons in its outer shell.
What is the maxium amount of electrons in a electron valence ring?
The maximum number of electrons that can occupy a valence shell, or electron valence ring, is eight, according to the octet rule. This rule states that atoms are most stable when they have eight electrons in their outermost shell. However, the first electron shell can hold a maximum of only two electrons.
What is the optimum number of electrons for phosphorous to possess in its outermost closed shell?
The optimum number of electrons in the outermost valence shell for phosphorus atoms is eight, known as an octet. Unbonded phosphorus atoms have 5 valence electrons and undergo chemical bonding in order to gain the other 3, either by covalent bonding or by ionic bonding.
An atom is stable when its outermost orbit is?
An atom is stable when its outermost orbit, or valence shell, is complete with the maximum number of electrons it can hold according to the octet rule. This typically means having eight electrons for most elements, except for hydrogen and helium which only need two electrons in their outer shell to be stable.
How many electrons normally does it take to make an atom chemically stable what is the exception to this rule?
The number of electrons must be eight.
An atom is stable when it?
An atom is stable when the number of protons equals the number of electrons, creating a balanced electrical charge. Additionally, stable atoms have filled outer electron shells that follow the octet rule, meaning they have eight electrons in their outermost shell.
When an atom has eight valence electrons it has a stable arrangement called what?
stable electronic configuration
Does sn gain or lose electrons?
Sulfur typically gains electrons to form a stable electron configuration. It can gain up to two electrons to achieve a full valence shell of eight electrons.
What does it mean if an element has 8 electrons?
it has a full octet
What characteristic of any single atom determines the number of covalent bonds that it can form?
The number of valence electrons in an atom determines the number of covalent bonds it can form. Atoms tend to fill their valence shell by sharing or gaining electrons to achieve a stable electron configuration. Typically, atoms will form covalent bonds to complete their valence shell with eight electrons (octet rule), which dictates the number of bonds that can be formed.
How many electrons do phosphorus borrow?
Phosphorus typically borrows three electrons to achieve a full outer shell of eight electrons. This allows phosphorus to reach a stable electron configuration similar to the noble gas neon.
How many electrons are called are needed in the outer energy level of most atoms for the atom to be stable?
Most atoms are stable when they have a full outer energy level, which typically consists of 8 electrons. This is known as the octet rule. However, some smaller atoms, such as hydrogen and helium, are stable with only 2 electrons in their outer energy level.
Is the most atom more or less stable when they have eight valence electrons true or false?
less stable
Do Boron gain or lose electrons?
Boron typically loses electrons to achieve a stable electron configuration. It has three valence electrons in its outer shell, and by losing these three electrons, it can attain a full outer shell with eight electrons. This results in a +3 oxidation state for boron, as it loses three electrons to become more stable.
How many electrons does calcium need to get eight valence electrons?
Calcium has two valence electrons in its outer shell. To achieve a stable octet configuration of eight valence electrons, it needs to lose these two electrons rather than gain any. Therefore, calcium does not need to gain any electrons; instead, it will typically lose two to achieve stability.
