a. What is the shape of i. s orbital ii. P orbital
b. Which of the following orbital are spherically symmerical ?
i. `p_(x) ` ii. `s` iii. `p_(y)`

Explanation

### Step-by-Step Solution:

**i. s orbital:**
- The s orbital has a spherical shape. It is symmetric about the nucleus, meaning that it looks the same in all directions from the nucleus. The electron density is uniformly distributed around the nucleus.

**ii. p orbital:**
