Question

a proton is added to carbon? a proton is removed from carbon a neutron is added to carbon? a neutron is removed from carbon? an electron is added to carbon? an electron is removed from carbon? here are three isotopes of an element: (_{6}^{12}c) (_{6}^{13}c) the element is the number 6 refers to the the numbers 12, 13, and 14 refer to the how many protons and neutrons are in the first isotope?

Explanation:

Step1: Adding/removing neutron changes isotope.

Adding neutron to carbon gives a carbon - isotope, removing gives a carbon - isotope.

Step2: Adding electron makes anion.

Adding electron to carbon makes C⁻.

Step3: Removing electron makes cation.

Removing electron from carbon makes C⁺.

Step4: Identify element from isotope notation.

Element is carbon as atomic number is 6. Number 6 is atomic number, 12, 13 are mass numbers. First isotope ₆¹²C has 6 protons and 6 neutrons.

Answer:

A neutron added: Carbon - isotope; A neutron removed: Carbon - isotope; An electron added: C⁻; An electron removed: C⁺; Element: Carbon; Number 6: Atomic number; 12, 13, 14: Mass numbers; First isotope: 6 protons and 6 neutrons
