Question

hydrogen
symbol:
no. of electrons:
atomic number:
atomic mass:
p=
n=

Explanation:

Step1: Determine the number of protons (p)

The atomic number of an element is equal to the number of protons in its nucleus. For hydrogen, the atomic number is 1. So, \( p = 1 \).

Step2: Determine the number of neutrons (n)

The atomic mass (approximate, since the most common isotope is considered here) of hydrogen is 1. The formula for atomic mass \( A=p + n \). Rearranging for \( n \), we get \( n=A - p \). Substituting \( A = 1 \) and \( p = 1 \), we have \( n=1 - 1=0 \).

Answer:

\( p = 1 \), \( n = 0 \)
