The number of protons, electrons, and neutrons for 1 7 8 O 2 - should be determined. Concept Introduction: The general atomic symbol of an element is: A Z X Where A is mass number of an atom, Z is atomic number , and X is the atomic symbol of an element. The number of protons of an atom is equal to the atomic number of an atom. For a neutral atom, the number of protons and neutrons are same whereas the mass number of an atom is total sum of number of protons and neutrons of an atom.

Answer 1

Question

Chapter 4, Problem 74QAP

Interpretation Introduction

Interpretation:

The number of protons, electrons, and neutrons for ¹⁷ ₈ O² - should be determined.

Concept Introduction:

The general atomic symbol of an element is:

^A _Z X

Where A is mass number of an atom, Z is atomic number, and X is the atomic symbol of an element.

The number of protons of an atom is equal to the atomic number of an atom. For a neutral atom, the number of protons and neutrons are same whereas the mass number of an atom is total sum of number of protons and neutrons of an atom.
