Identify and name the metal whose electronic configuration are given below :
`2,8,1`

Explanation

To identify and name the metal with the electronic configuration `2, 8, 1`, we can follow these steps:

### Step 1: Understand Electronic Configuration
The electronic configuration `2, 8, 1` indicates the distribution of electrons in the shells of an atom. The first number (2) represents the number of electrons in the first shell (K shell), the second number (8) represents the number of electrons in the second shell (L shell), and the last number (1) represents the number of electrons in the third shell (M shell).

### Step 2: Count the Total Number of Electrons
To find the total number of electrons, we add the numbers in the electronic configuration:
- 2 (K shell) + 8 (L shell) + 1 (M shell) = 11 electrons.
