Neon, a noble gas, has a complete outer energy level with eight electrons, which is its optimal configuration for stability. Therefore, it does not need to form any bonds to fill its outer energy level, as it is already "full." In fact, neon is known for its lack of chemical reactivity due to this stable electron configuration.
Nitrogen has five electrons in its outer energy level (the second shell) and needs three more electrons to fill it, achieving a stable octet. Therefore, nitrogen typically forms three covalent bonds with other elements to complete its outer shell. This property is reflected in common compounds like ammonia (NH₃) and nitrogen trichloride (NCl₃).
Chlorine has seven electrons in its outer energy level (valence shell). To achieve a full outer energy level, which requires eight electrons, chlorine needs to gain one electron. Therefore, chlorine typically gains one electron to fill its outer energy level and achieve stability.
Beryllium has two electrons in its outermost energy level (the 2s subshell). To achieve a full outer energy level, which requires a total of eight electrons (octet rule), beryllium typically loses these two outer electrons. By losing these electrons, beryllium achieves a stable electron configuration similar to that of the nearest noble gas, neon.
Yes.
no. of electrons to fill an energy level = 2n2. = 2x32 = 18
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
