A proton is made up of two up quarks( $u^{+\frac23}$ ) and a down quark ( $d^{-\frac13}$ ), so $p^+=1$ since $2\times \dfrac{2}{3}-\dfrac{1}{3}=1.$ Also, an electron is $e^-=-1$ , so $p^++e^-=0$ . This is a hydrogen atom.

In Chemistry, $p^+$ represents a proton which has a charge of $+1 e$ (where $e = 1.60217662 × 10^{-19}$ coulombs), and $e^-$ represents an electron which has a charge of $-1 e$ .

Therefore, $(p^+) + (e^-) = (+1 e) + (-1 e) = \boxed{0}$ .

Fact: It is verified from a lot of experiments, that a proton and electron have an equal charge but opposite in magnitude.

Convention: Conventionally, electron's charge is taken as -1 thus proton's charge would be +1

• Thus, adding the charges algebraically, we find the answer as follows:

$\boxed{{ p }^{ + }+e^{ - }}$

$\boxed{=1+(-1)}$

$\boxed{=1-1}$

$\boxed{0}$

$\textbf{Basic Info - }$

A $\color{#3D99F6}proton$ has $\color{#3D99F6}+ve$ charge, while an $\color{#D61F06}electron$ has $\color{#D61F06}-ve$ charge

$\textbf{Using info to find answer}$

When we add 1 and -1, we get 0, in the same way - adding a $\color{#3D99F6}positive$ charge to a $\color{#D61F06}negative$ charge results in $\color{grey}neutral$ charge = 0

$\textbf{Bonus Info - }$

A proton and an electron make a hydrogen atom.

A proton has 2 up quarks (u^{\frac{+2}{3}}\​) and a down quark (d^{\frac{-1}{3}}\​), which add up to +1 charge

As protons have positive charge and electrons have negative charges, when their values are equal in an atom, it becomes neutral (i.e. $0$ )

Same thing goes with static charges, positive plus negative results in a neutral
