Question

practice make the atoms. fill in the missing information: carbon element name how many? 6 p⁺ 7 n° 6 e⁻ how many stable isotopes of this element can you make? 2 checkone stable unstable

Explanation:

Step1: Identify element symbol

The symbol for carbon is C, which is already correctly filled in the given image.

Step2: Recall number of stable isotopes

Carbon has 2 stable isotopes, which are carbon - 12 and carbon - 13.

Step3: Determine charge state

The number of protons ($p^+$) is 6, the number of neutrons ($N^0$) is 7, and the number of electrons ($e^-$) is 6. Since the number of protons equals the number of electrons, the atom is neutral.

Step4: Fill in missing check - box

Since there are 2 stable isotopes, we check the "Stable" box.

Answer:

Check the "Stable" box.
