Question

complete the table to determine the nuclear symbol for this neutral atom.

nuclear symbol | subatomic particles
yellow boxes | protons: 48
| neutrons: 65
| electrons: 48

to which element does this atom belong?
yellow dropdown

Explanation:

Step1: Find mass number

Mass number = protons + neutrons = \( 48 + 65 = 113 \)

Step2: Identify element by atomic number (protons = 48)

Atomic number 48 corresponds to Cadmium (Cd).

Step3: Write nuclear symbol

Nuclear symbol is \( \ce{_{48}^{113}Cd} \) (top number: mass, bottom: atomic number, symbol: Cd)

Answer:

Nuclear symbol: \( \boldsymbol{_{48}^{113}\text{Cd}} \), Element: Cadmium (Cd)
