What two elements only need two valence electrons to be happy?
The two elements that only need two valence electrons to achieve a stable electron configuration are helium (He) and beryllium (Be). Helium, being a noble gas, has a full outer shell with two electrons, making it stable. Beryllium, a metal, typically forms compounds by sharing or losing its two valence electrons to achieve a stable state, similar to that of helium.
Which two elements only need two valence electrons to be happy?
The two elements that only need two valence electrons to achieve a full outer shell are helium (He) and beryllium (Be). Helium, a noble gas, has a complete outer shell with two electrons, which satisfies the octet rule in a duet configuration. Beryllium, on the other hand, typically forms compounds by sharing or losing its two valence electrons to achieve stability.
Which group of elements forms bonds by using their six valence electrons?
The group 16 elements have 6 valence electrons. However, they generally only have two unpaired electrons available for bonding.
How do valence electrons tell you what elements will bond together?
Valence electrons are involved in bonding between elements because they determine an element's reactivity. Elements with a similar number of valence electrons tend to bond together to achieve a stable electron configuration, either by losing, gaining, or sharing electrons. This interaction allows elements to form compounds with one another.
Why are elements in different families?
Elements on the Periodic Table of Chemical Elements are separated into groups/families based on their valence electrons.Every atom has electrons. The ones in the outermost energy level(shell) are the valence electrons. These are the only electrons used in chemical bonds and compounds.PainRain
How many valence electrons do most elements need to become stable?
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.

How do you find valence electons on a periodic table?
To determine the number of valence electrons on the periodic table you look at columns 1,2 and 13-18. For columns 13-18 you just need to subtract ten from column number. For example, column 13 elements have 3 valence electrons. Most chemistry courses avoid the transition elements but you only need to consider the outer orbital of electrons.

How many valence electrons will result in chemical stability for an atom?
A full outer shell of electrons typically results in chemical stability for an atom. This corresponds to 8 valence electrons for most atoms (except hydrogen and helium, which only need 2 valence electrons for stability).
How many valence electrons can an atom have?
An atom can have a maximum of 8 valence electrons in its outermost energy level, except for hydrogen and helium, which can only have a maximum of 2 valence electrons. The number of valence electrons determines an atom's chemical properties and reactivity. Elements in the same group on the periodic table have the same number of valence electrons.
Do only outer shells gain or lose electrons with other atoms?
Yes. Only the valence shell will interact with other atoms. This is how different elements are different from eachother. The electrons under the valence shell are never touched. Yes. Only the valence shell will interact with other atoms. This is how different elements are different from eachother. The electrons under the valence shell are never touched.
What is a noble gas but does not have 8 valence electrons?
Helium is the only noble gas that doesn't have 8 valence electrons. It only has 2.
Which elements contain multiple valences electron?
Almost all elements have multiple valence electrons, there are only 7 that don't. They are: hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. The elements have 1 valence electron. All other elements have anywhere from 2 to 8 valence electrons
