Consider an element `""_(15^(31)X` and answer the following questions
Is it a metal or a non-metal?

Explanation

To determine whether the element \( _{15}^{31}X \) is a metal or a non-metal, we can follow these steps:

### Step 1: Identify the Atomic Number
The atomic number of the element \( X \) is given as 15. This means that the element has 15 protons and, in a neutral atom, also 15 electrons.

### Step 2: Write the Electronic Configuration
To find out the electronic configuration, we distribute the 15 electrons among the available energy levels (shells):
- The first shell (K) can hold a maximum of 2 electrons.
