Yes.
no. of electrons to fill an energy level = 2n2. = 2x32 = 18
noble gases
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
Fluorine needs 8 valence electrons to have a filled outer energy level, following the octet rule. Fluorine naturally has 7 valence electrons, so it only requires one more electron to achieve a stable octet configuration.
Nitrogen would have three bonds in order to fill its valence shell.
Sulfur has six valence electrons, so it needs two more electrons to fill its outer energy level. This means that sulfur typically forms two covalent bonds with other elements in order to achieve a full valence shell of eight electrons.
Sulfur has 6 electrons in its outer energy level. This means it needs 2 more electrons to fill its outer energy level, for a total of 8 electrons.
Atoms with fewer than 8 valence electrons can fill their outermost energy level by forming chemical bonds with other atoms. For example, magnesium can lose 2 electrons to achieve a full outer energy level, becoming a +2 cation. Conversely, sulfur can gain 2 electrons to fill its outer energy level, becoming a -2 anion. Both processes result in stable, filled outer energy levels for the atoms involved.
8 electrons
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
The group that needs one more electron to fill its outer energy level is the group of elements located on the right side of the periodic table known as Group 17, or the Halogens. These elements have seven valence electrons and are just one electron short of a full outer energy level.
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.
Atoms form chemical bonds to achieve a more stable and lower energy state. This can be achieved by sharing electrons (covalent bonds) or transferring electrons (ionic bonds) with other atoms. For example, in a water molecule (H2O), oxygen forms covalent bonds with hydrogen atoms to fill its outer electron shell and become more stable. In sodium chloride (NaCl), sodium transfers an electron to chlorine to form an ionic bond and achieve a stable electron configuration.
It needs to lose one electron so that it can have 8 electrons in its outer orbital
Look at the first element on the periodic table. The first energy level holds only two electrons, so Helium has filled its outer energy level. Atoms with an outer energy level that is not fill will fill it up by bonding with other atoms and sharing electrons.
Yes, electron sharing typically occurs in the outermost energy level, known as the valence shell. This is because atoms strive to fill their valence shell to achieve stability by completing their octet (8 electrons for most elements).
