How many valence electrons do each of the following ions have: K+ ,Se2-? Briefly describe your rationale. Among the following, determine which have similar chemical properties: Na, Mg, K, K+. Briefly explain Consider a 1s orbital and a 2s orbital. Identify which orbital is further from the nucleus and also which orbital has a lower potential energy. Most of calcium in nature exists as 40Ca2+, but there is a measurable amount of isotopes with mass number of 42, 43 and 44. Write the nuclear symbol (just one) that represents a mixture of these isotopes.

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.
