The chemical symbol for an element with an electron configuration that ends with np² is represented by the group 14 elements in the periodic table. For example, if n = 2, the element is silicon (Si); if n = 3, it is germanium (Ge); and if n = 4, it is tin (Sn). Each of these elements has an outer electron configuration that concludes with np².
An element with an electron configuration that ends with np², where n is any principal quantum number, would be in group 14 of the periodic table. Examples include silicon (Si) with the configuration [Ne] 3s² 3p² (n=3) and lead (Pb) with the configuration [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p² (n=6). These elements typically exhibit properties of metalloids or metals and are known for forming covalent bonds.
The electron configuration ending in np² indicates that there are two electrons in the p subshell of the outermost energy level. This typically corresponds to elements in group 14 of the periodic table, such as silicon (Si) and germanium (Ge). For example, the complete electron configuration for silicon is 1s² 2s² 2p⁶ 3s² 3p².
The elemental selenium in selenium dioxide monohydrate exists as Se(IV) in the +4 oxidation state. It is bonded to two oxygen atoms in a linear configuration. The oxygen atoms are bound to the selenium atom in a double bond.
Elements in Group 2 of the periodic table will have an electron configuration that ends in s2. This group includes elements such as beryllium, magnesium, and calcium. They have two electrons in their outermost s sublevel.

The electron configuration ending in np² indicates that there are two electrons in the p subshell of the outermost energy level. This typically corresponds to elements in group 14 of the periodic table, such as silicon (Si) and germanium (Ge). For example, the complete electron configuration for silicon is 1s² 2s² 2p⁶ 3s² 3p².
The general electronic configuration of p block elements is ns2 np1-6. This means that the outermost electron shell of p block elements contains electrons in either the np1, np2, np3, np4, np5, or np6 orbitals.

The element with the electron configuration of 2s2 2p4 is Oxygen (O), which has 8 electrons in total.
The 3p1 electron configuration belongs to phosphorus with the electron configuration 1s2 2s2 2p6 3s2 3p1. This means that phosphorus has 15 electrons, with the last electron occupying the 3p subshell.
The atomic number for sulfur is 16. That means that its electron configuration is 1s2 2s2 2p6 3s2 3p4. This can be shortened to [Ne] 3s2 3p4, which shows you that 3s2 3p4 is how sulfur's electron configuration ends.
