**Question:**How does the number of valence electrons change as one moves from left to right across any group on the periodic table?**Options:**- **A:** It increases by one.- **B:** It decreases by one.- **C:** It stays the same.- **D:** The relationship cannot be predicted.Explanation: As elements on the periodic table are arranged in rows called periods, moving from left to right across a period generally leads to an increase in the number of valence electrons by one per element. Understanding this pattern is crucial for predicting the chemical behavior and bonding potential of elements.

Along the period (from left to right ) : When one moves from left to right ; the atomic number of…

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.
