Question

Identify the element below and give the symbols of the other elements in its group. [ar] 4s23d104p2 element symbol: all other elements in its group: ga (only) sn, pb ga, as, se, br, kr c, si, sn, pb

Answer 1

The identified element is Ge (Germanium). All other elements in its group are Si, Sn, and Pb.

Step-by-step explanation:

The element with the electron configuration [Ar] 4s23d104p2 is Germanium (Ge). In the periodic table, elements in the same group share similar chemical properties. Germanium belongs to Group 14, which includes silicon (Si), tin (Sn), and lead (Pb). These elements exhibit a pattern in their electron configurations where the outermost electron shell contains 4 electrons.

The pattern is [noble gas] ns2np2, where n is the principal quantum number of the outermost shell. Silicon, tin, and lead, along with Germanium, all follow this configuration, showcasing the group's characteristic valence shell structure. Understanding the periodic table and electron configurations allows for the identification of elements and recognition of patterns within groups, aiding in predicting chemical behavior and properties.
