Analyze the information. oxygen-15 is an isotope that has an atomic number of 8. based on the information, select the answer choices that are true statements. (select all that apply.) a. oxygen-15 has 8 protons b. oxygen-15 has 7 electrons c. oxygen-15 has 8 neutrons d. oxygen-15 has 7 neutrons

Option (A) and (D) are correct.

Explanation:

Atomic number means the number of protons holded by an atom. On the other hand, atomic mass means the sum of total number of protons and neutrons holded by an atom.

For example, in an isotope of oxygen as oxygen-15 with an atomic number 8 means that there are 8 protons.

So, number of neutrons present in oxygen-15 will be as follows.

                    Atomic mass = no. of protons + no. of neutrons

                            15 = 8 + no. of neutrons

                    no. of neutrons = 15 - 8 = 7

Hence, this isotope of oxygen atom has 8 protons and 7 neutrons.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
