Answer
Because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. So, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.

Answer:
Volume required from standard solution = 4675 mL
Explanation:
Given data:
Final volume = 75.0 mL
Final molarity = 130 M
Molarity of standard solution = 2.000 M
Volume required from standard solution = ?
Solution:
We use the formula,
C₁V₁ = C₂V₂
here,
C₁ = Molarity of standard solution
V₁ = Volume required from standard solution
C₂ = Final molarity
V₂ = Final volume
Now we will put the values in formula,
C₁V₁ = C₂V₂
2.000 M × V₁ = 130 M × 75.0 mL
V₁ = 9750 M. mL / 2.000 M
V₁ = 4675 mL
