what are the differences between the elements in group 5a?
235640
The Group 5A elements have five valence electrons in their highest-energy orbitals (ns2np3). Nitrogen, phosphorus, and arsenic can form ionic compounds by gaining three electrons, forming the nitride (N3-), phosphide (P3-) and arsenide (As3-) anions, but they more frequently form compounds through covalent bonding.

Group 1A elements have 1 valence electron. Group 2A elements have 2 valence electrons. Group 3A elements have 3 valence electrons.

Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Group 2 elements share common characteristics. Each metal is naturally occurring and quite reactive. These metals are silver and soft, much like the alkali metals of Group 1. These metals also react with water, though not as vigorously.

In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.

The Group 6A elements have six valence electrons in their highest-energy orbitals (ns2np4). This is only two electrons away from having a full octet of eight electrons, so many of these elements form anions having -2 charges: oxide, O2-; sulfide, S2-, selenide, Se2-, etc.

Group 2A elements are the alkaline earth metals and all have two electrons in the outermost energy level because their electron configuration ends in s2. Group 5A elements all have five electrons in the outermost energy level because their electron configuration ends in s2p3.

Due to their smaller atomic radii as compared to alkali metals, group 2 elements have higher ionization energies than alkali metals but lower than the remaining elements. At STP, these elements are shiny, soft, silvery-white metals that have industrial as well as biological importance.

All the Group 1 elements - lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr) - have one electron in the outer shell. The Group 7 elements - fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At) - have seven electrons in the outer shell.

This family consists of the elements nitrogen, phosphorus, arsenic, antimony, bismuth, and ununpentium (N, P, As, Sb, Bi, and Uup, respectively). Each member of this family contains five valence electrons. Due to these valence electrons, the members of Group 15 are able to form double and triple bonds.

The fifth energy level contains: 5s (which holds 2 electrons), 5p (which holds 6), 5d (holds 10), and 5f (holds 14) for a total of 32 electrons. After that, the fifth, sixth, and seventh energy levels also have four sublevels each. 6.

Chemists often make general statements about the properties of the elements in a group using descriptive names with historical origins. For example, the elements of Group 1 are known as the alkali metals, Group 2 are the alkaline earth metals, Group 17 are the halogens, and Group 18 are the noble gases.

Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.

About the Group Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).
