QuestionAn atom with 9 protons and 10 electrons is: A) Nonstoichiometric B) An ion C) A cathode ray D) An alpha particle E) Neutrally charged.

Studdy Solution

STEP 1

Assumptions1. The atom has nine protons. The atom has ten electrons

STEP 2

We need to understand that protons carry a positive charge and electrons carry a negative charge.

STEP 3

The charge of an atom is determined by the difference between the number of protons (positive charges) and electrons (negative charges).
Charge=Number of protons−Number of electronsCharge = Number\, of\, protons - Number\, of\, electrons

STEP 4

Plug in the given values for the number of protons and electrons to calculate the charge.
Charge=9−10Charge =9 -10

STEP 5

Calculate the charge of the atom.
Charge=9−10=−1Charge =9 -10 = -1

STEP 6

Interpret the result. A negative charge indicates that the atom has more electrons than protons, which makes it an ion. Therefore, the answer is B) An ion.
