Question

question 4 neon has protons neutrons electrons

Explanation:

Step1: Identify atomic number

The atomic number of an element is the number of protons. For neon (Ne), the atomic number is 10, so the number of protons is 10.

Step2: Calculate neutrons

The mass - number is approximately 20.180. Rounding it to 20. The number of neutrons = mass - number - atomic number. So, neutrons = 20 - 10=10.

Step3: Determine electrons

In a neutral atom, the number of electrons is equal to the number of protons. Since neon is neutral and has 10 protons, it has 10 electrons.

Answer:

Protons: 10
Neutrons: 10
Electrons: 10
