To determine the number of protons, neutrons, and electrons in a gallium ion with a +3 charge, we follow these steps:
-
Determine the Number of Protons: The atomic number of gallium (Ga) is 31, which means it has 31 protons.
-
Determine the Number of Neutrons: The mass number of gallium is 70. The number of neutrons can be found by subtracting the atomic number from the mass number:
\[ \text{Number of neutrons} = \text{Mass number} - \text{Atomic number} = 70 - 31 = 39 \]
-
Determine the Number of Electrons: A neutral atom of gallium would have an equal number of electrons as protons, which is 31. However, since we are dealing with a gallium ion with a +3 charge, it has lost 3 electrons:
\[ \text{Number of electrons} = 31 - 3 = 28 \]
So, the breakdown for the gallium ion with a +3 charge is:
- Protons: 31
- Neutrons: 39
- Electrons: 28
Therefore, the table representing these values would look like this:
| Property | Number | |------------|--------| | Protons | 31 | | Neutrons | 39 | | Electrons | 28 |
