Question

protons: 9
neutrons: 10
electrons: 10
find the element:
is it:
○ neutral atom
○ ion

Explanation:

Step1: Recall element - proton number relation

The atomic number of an element is equal to the number of protons. Here, the number of protons is 9.

Step2: Identify the element

Looking at the periodic - table, the element with atomic number 9 is Fluorine (F).

Step3: Determine if it is a neutral atom or ion

In a neutral atom, the number of electrons is equal to the number of protons. Here, the number of protons is 9 and the number of electrons is 10. Since the number of electrons is not equal to the number of protons, it is an ion.

Answer:

Element: Fluorine (F)
Is it: Ion
