# Proton Count of Element with Max Unpaired Electrons in 2P Subshell

• xiphoid
In summary, the number of protons is the total amount of positively charged particles in the nucleus of an atom, written as a subscript to the left of the element's symbol. It determines an element's atomic mass, properties, and position on the periodic table. The number of protons cannot be changed without changing the element's identity.

## Homework Statement

The number of protons in nucleus of an element having maximum unpaired electrons in its 2P subshell are:

## Homework Equations

Number of protons = no. of electrons in an neutral atom

## The Attempt at a Solution

Maximum unpaired E.C. should 1s22s22p 3
Then, no. of protons should be 7.

True

## What is the definition of "number of protons"?

The number of protons is the total amount of positively charged particles in the nucleus of an atom. It determines the element's atomic number and is used to identify and classify different elements.

## How is the number of protons written in an element's symbol?

The number of protons is written as a subscript to the left of the element's symbol. For example, the element carbon has 6 protons, so its symbol is written as "C" with the number 6 written as a subscript to the left of the symbol.

## How does the number of protons affect an element's properties?

The number of protons determines an element's atomic mass and thus, its chemical and physical properties. It also determines the number of electrons in a neutral atom, which affects its reactivity and bonding capabilities.

## What is the relationship between an element's number of protons and its position on the periodic table?

The number of protons increases as you move from left to right on the periodic table. This is because the elements are arranged in order of increasing atomic number. The number of protons also determines an element's group and period on the periodic table.

## Can the number of protons in an element change?

No, the number of protons in an element is constant and cannot be changed without changing the element itself. This is because the number of protons determines the element's identity and distinguishes it from other elements.
