Question

complete the table to determine the nuclear symbol for this neutral atom.
nuclear symbol subatomic particles
protons: 9
neutrons: 10
electrons: 9
to which element does this atom belong?

Explanation:

Step1: Recall atomic number definition

Atomic number ($Z$) is number of protons. Here, protons = 9, so $Z = 9$.

Step2: Identify element by atomic number

Element with atomic number 9 is Fluorine (F). Mass number ($A$) = protons + neutrons = $9 + 10 = 19$. Nuclear symbol: $\ce{^{19}_{9}F}$.

Answer:

Nuclear symbol: $\boldsymbol{\ce{^{19}_{9}F}}$; Element: Fluorine (F)
