Just one: silicon. Please see the link.
All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
Yes, understanding the electron configurations of elements can help explain the arrangement of elements on the periodic table. Electron configurations determine an element's chemical properties, reactivity, and position within the table. The periodic table is organized based on recurring patterns in electron configurations, such as the filling of energy levels and sublevels.
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
The elements with electron configurations that end in ns 2 and np 5 are found in Group 17 of the periodic table, known as the halogens. This group includes elements such as fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Elements in a group have the same number of valence electrons, giving them similar electron configurations. The electron configurations differ by the number of filled inner shells, leading to a trend in chemical reactivity within the group. The periodic table is organized based on these similarities in electron configurations within groups.

Elements with similar electron configurations are placed in the same group.
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
Each neutral atom has a specific electron cofiguration.
All halogens or group 17 elements.

Elements in a group have the same number of valence electrons, giving them similar electron configurations. The electron configurations differ by the number of filled inner shells, leading to a trend in chemical reactivity within the group. The periodic table is organized based on these similarities in electron configurations within groups.
The chemical behavior of different elements is determined by their electron configurations. Elements with similar electron configurations exhibit similar chemical behavior. For example, elements in the same group of the periodic table tend to have similar chemical properties due to their shared electron configurations.
The electron configurations of LiF will be the same as the electron configurations of atoms in Group 18 (noble gases) because Li will lose its single electron to attain a stable octet similar to the noble gases, while F will gain an electron to achieve a complete valence shell.
The elements with electron configurations ending in ns2np5 are the halogens in Group 17 of the periodic table. This includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). These elements have seven valence electrons and readily gain an electron to achieve a stable octet configuration.
