What else can I help you with?
Do all nonmetals have a completelyfull Valence shell of electrons?
There is no set amount of valence electrons for nonmetals. The amount of valence electrons a nonmetal has is determined by the number of electrons on the outer shell of the atom.
What is the the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
The symbol for an element that does not need eight electrons to have a full set of valence electrons is typically found in Group 1 or Group 2 of the periodic table. Examples include lithium (Li) from Group 1 and beryllium (Be) from Group 2. These elements follow the duet rule or satisfy the octet rule in a different way.
What do you notice in the number of valence electrons of metals non-metals and noble gases?
Metals typically have one to three valence electrons, which they can easily lose to form positive ions. Non-metals usually have four to eight valence electrons, often gaining or sharing electrons to achieve a full outer shell. Noble gases possess a complete set of eight valence electrons (except for helium, which has two), making them chemically stable and largely unreactive. This difference in valence electron configuration explains the distinct chemical behaviors of these groups.
How many valence electrons do the boron group have?
Boron is located in group 3A. It is group 13 in modern notation. This set of elements have three valence electrons.Boron is in the 13th group in the periodic table. Elements in this group has 3 electrons in the outermost energy level. That means they have 3 valence electrons.
A set of 8 valence electrons is called?
This is called an "octet" of electrons. It could also be called a "closed shell", since it is characteristic of the outer shell of noble gas atoms.
How many electrons make up a full set of valence electrons?
A full set of valence electrons typically consists of 8 electrons, except for hydrogen and helium, which have a full valence shell with 2 electrons.
How will atoms with 5 valence electrons achieve a full set of valence electrons?
They will gain 3 electrons from something with 3 valence electrons.
How with 4 valence electron will achieve a full set of valence electron?
An atom with 4 valence electrons will have to either gain 4 electrons or lose 4 electrons to achieve a full set of eight electrons.
What states that atoms tend to gain lose or share electrons in order to achieve a full set of valence electrons typically?
The octet rule.
Do all nonmetals have a completelyfull Valence shell of electrons?
There is no set amount of valence electrons for nonmetals. The amount of valence electrons a nonmetal has is determined by the number of electrons on the outer shell of the atom.
Can helium have a full set of valence electrons?
It does.
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.
Why are the valence electrons located in an atom?
If you mean "where are the valence electrons" then they are flying around the outside of the atom.If you mean "why" then I don't know. they're just there to be the outermost set of electrons.
How man valence electrons does neon have?
Neon has 8 valence electrons. This is because neon is in the 8th group (or 18th column) of the periodic table, and elements in this group have a full set of 8 valence electrons.
How many electrons does phosphrous have to gain or loose to have 8 valence?
Phosphorus, with 5 valence electrons, needs to gain 3 electrons to have a full set of 8 valence electrons. This would allow it to achieve a stable octet configuration, resembling the noble gas configuration of argon.
Which group has a complete set of valence electrons in their outermost energy level?
Noble gases have a complete set of valence electrons in their outermost energy level, which is why they are known to be stable and unreactive.
How can an atom that has 5 valence electrons achieve a full set of valence electrons?
An atom with 5 valence electrons can achieve a full set of 8 valence electrons by either gaining 3 electrons through bonding with other atoms or losing 5 electrons by forming ionic bonds. Another option is to share electrons with other atoms through covalent bonding to reach a stable octet.
