Question

complete the table to determine the nuclear symbol for this neutral atom
nuclear symbol | subatomic particles
yellow boxes | protons: 13
| neutrons: 14
| electrons: 13
to which element does this atom belong?
yellow dropdown

Explanation:

Step1: Recall atomic number definition

Atomic number ($Z$) = number of protons. Here, protons = 13, so $Z = 13$.

Step2: Identify element by atomic number

Elements are defined by atomic number. Atomic number 13 corresponds to Aluminum (Al). Also, mass number ($A$) = protons + neutrons = $13 + 14 = 27$. The nuclear symbol is $^{27}_{13}\text{Al}$.

Answer:

Nuclear symbol: $^{27}_{13}\text{Al}$; Element: Aluminum (Al)
