Answer 1

To determine the number of subatomic particles (protons, electrons, neutrons) and related properties (charge and mass number) for each given nuclide, we can follow these steps:

1. Determine the number of protons from the atomic number (the number of protons is unique to each element).
2. Calculate the number of neutrons using the formula: Neutrons = Mass Number - Protons.
3. Determine the number of electrons based on the charge of the atom (neutral atoms have equal protons and electrons; positive charge means there are fewer electrons, and negative charge means there are more electrons).
4. The mass number is a count of the total number of protons plus neutrons.

Let's calculate for each provided nuclide:

### 1. \(^{23}\text{Na}^{+3}\)
- Protons: 11 (sodium has atomic number 11)
- Electrons: 8 (11 protons - 3 charge = 8 electrons)
- Neutrons: 12 (Mass number 23 - Protons 11 = 12 neutrons)
- Charge: +3
- Mass Number: 23

### 2. \(^{16}\text{N}^{-2}\)
- Protons: 7 (nitrogen has atomic number 7)
- Electrons: 9 (7 protons + 2 charge = 9 electrons)
- Neutrons: 9 (Mass number 16 - Protons 7 = 9 neutrons)
- Charge: -2
- Mass Number: 16

### 3. \(^{9}\text{Li}^{+1}\)
- Protons: 3 (lithium has atomic number 3)
- Electrons: 2 (3 protons - 1 charge = 2 electrons)
- Neutrons: 6 (Mass number 9 - Protons 3 = 6 neutrons)
- Charge: +1
- Mass Number: 9

### 4. \(^{37}\text{Cl}^{-2}\)
- Protons: 17 (chlorine has atomic number 17)
- Electrons: 19 (17 protons + 2 charge = 19 electrons)
- Neutrons: 20 (Mass number 37 - Protons 17 = 20 neutrons)
- Charge: -2
- Mass Number: 37

Here is a summary of answers:

#### \(^{23}\text{Na}^{+3}\)
- Protons: 11
- Electrons: 8
- Neutrons: 12
- Charge: +3
- Mass Number: 23

#### \(^{16}\text{N}^{-2}\)
- Protons: 7
- Electrons: 9
- Neutrons: 9
- Charge: -2
- Mass Number: 16

#### \(^{9}\text{Li}^{+1}\)
- Protons: 3
- Electrons: 2
- Neutrons: 6
- Charge: +1
- Mass Number: 9

#### \(^{37}\text{Cl}^{-2}\)
- Protons: 17
- Electrons: 19
- Neutrons: 20
- Charge: -2
- Mass Number: 37
