PhysicalEasyNEET: 2-3 Q3D

Atomic Orbitals — s, p, d Shapes in 3D

Atomic Structure

Visualize s, p, and d orbital shapes in 3D. Toggle between orbitals and understand why electron density takes these specific forms — the building blocks of every chemical bond.

How to use this lab

1Explorer ya Subshell tab choose karo.
21s, 2s, 2p, 3p, 3d — koi bhi orbital tap karo, shape change hoga.
3Drag karke lobes aur nodal planes 3D mein ghuma ke dekho.

What you're seeing

Orbital ka matlab path nahi — yeh wo region hai jahan electron milne ki probability sabse zyada hai. Explorer tab se koi bhi orbital (1s se 3d tak) pick karo aur uska shape aur node count dekho. Subshell tab se saare p ya saare d orbitals ek saath dekho — isi liye 3 p-orbitals = 6 electrons aur 5 d-orbitals = 10 electrons.

Key NEET facts

▸s orbital: Spherical, 0 nodes — 1s is the smallest, lowest-energy orbital
▸p orbital: Dumbbell, 1 angular node — three orientations (pₓ, p_y, p_z) → holds 6 electrons
▸d orbital: Cloverleaf, 2 angular nodes — five orientations → holds 10 electrons
▸Total nodes: n − 1 — radial nodes = n − l − 1, angular nodes = l

Memory trick

Shape stays the same as n grows — only size and node count increase. Total nodes = n − 1, always.
