You and your classmates have been given an electron configuration and need to identify what it is. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 You think this is the electron configuration for krypton, one classmate thinks it the calcium ion and another classmate thinks it's the selenium ion. Who is correct? Who is incorrect? Explain.
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
