Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals generally gain electrons to fill valence shells.
As you move across a period elements have the same number of?
Electron shells
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
Electrons found in the outer shell or orbital are called?
These electrons are called "outershell electrons" or "valence electrons."
What does Helium Neon Argon has in common?
They're nobile gases, meaning they have their outer valence electron shells filled and so practically no reactivity with other atoms. Helium has 2 electrons filling its valence shell whereas neon and argon have 8.
Do noble gases have valence shells?
Yes they have eight electrons in their valence shells. This is why they are not reactive. All elements have valence shells.
What predicts that atoms will react with each other to become more stable by filling their valence shells with eight electrons?
the octet rule does
Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals generally gain electrons to fill valence shells.
Does carbon have three electrons in its valence shells yes or no?
No, carbon has 4 valence electrons.
Elements on the right side of the periodic table with electrons sequentially filling the p orbitals of there valence shells are collectively known as the?
p-block
What are valence electrons and shells?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).
Elements on the right side of the periodict table with electrons sequentially filling the p orbitals of their valence shells are collectively known as the?
Representative Elements
What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.

What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
How many does hydrogen electrons in the outer shells?
Hydrogen has only one valence electrons.
How many valence shells in beryllium?
Beryllium has one valence shell containing two electrons.
