The number depends on what will fill the outer shell. It can be 2 or 8.

How many valence electrons will make an element chemically stable?
The number depends on what will fill the outer shell. It can be 2 or 8.
How many valence electrons will make an element happy or stable?
Most elements are stable with a full outer shell of electrons, typically with 8 electrons known as the octet rule. However, elements in the first shell can be stable with 2 electrons. This full outer shell results in a stable configuration similar to the noble gases, making the element happy or stable.
Does two valence electrons is a reactive or non reactive?
Two valence electrons make an atom chemically reactive because it wants to either gain or lose electrons to achieve a full valence shell. This makes it more likely to form bonds with other atoms to reach a stable electron configuration.
How many electrons do you need to make a Chlorine atom stable if you have 7 valence electrons?
You would need 1 more electron to make a Chlorine atom stable with 7 valence electrons. This additional electron would allow Chlorine to achieve a full valence shell of 8 electrons, following the octet rule.
How can you tell whether or not an element will react with others element?
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
What is the number of valence electrons needed to make an atom stable?
8 - s2 and p6
What does the number of valence electrons tell you about a given element?
If its positive it tells u that it has that number of valence electrons. If negative it tells you that it requires that number of electrons to make the valence electrons filled up/stable. If you know which Ion it is, you know the number of valence electrons of the neutral Atom. It corresponds to the group in the periodic table, the element is in. For example: Mg. It's in group 2, so it has 2 valence electrons. The oxidation number now tells you how many more or less electrons the atom has. For example: Mg(II) has 2 positive charges, hence two electrons less. That means it has 0 valence electrons. Take complete number of valence electrons, subtract the oxidation number and you get the number of valence electrons in the ion.
What are some charcteristics of element in group 18?
They are the noble gases. They have 8 valence electrons, so that means that they are stable, and they rarely make bonds with any other elements or compounds.
What is tin as a stable electron configuration?
Tin has 4 valence electrons. Because of this, Tin needs to lose the 4 electrons to make it stable. Thus the answer is SN4+
How can you tell whether or not an element will react other elements?
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
What chemical do valence electrons make when sharing?
Molecules or covalent compounds are formed by the sharing of valence electrons.
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
