How can an atom that has five valence electron achieve a full set of valence electron?
An atom with five valence electrons can achieve a full set of eight valence electrons by either gaining three electrons (to reach a stable octet) or losing three electrons to have a stable arrangement. This would result in the atom forming an ionic bond, such as in the case of boron transferring three electrons to become the boride ion.
What is true of electron configurations of the noble gases?
They all have a full set of valence 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.
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.
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.
Can helium have a full set of valence electrons?
It does.
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.
What is the best description of the end result of chemical bonding for most atoms?
Chemical bonding results in atoms forming stable molecules or compounds by sharing, gaining, or losing electrons to achieve a full outer electron shell. This process allows atoms to attain a more stable, lower-energy state by filling their outermost electron shell.
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.
How many electrons does chlorine need to have a full outer shell?
1 additional electron will give chlorine 8 in the valence. You can see in the Periodic table, that Chlorine is next to Argon ( 1 to the left of it) so it needs 1 more electron to have the same configuration as Argon.
Why is sodium fluoride a compound?
Na has 1 valence electron, Cl has 7. Therefor the 1 electron from the Na goes onto the Cl so that both have a full set of 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.
