Webthere are 53 protons, and 127 − 53 = 74 neutrons in each nucleus. Skill-Building Exercise How many protons and neutrons are in each atom? It is not absolutely necessary to indicate the atomic number as a subscript because each element has its own unique atomic number. Many isotopes are indicated with a superscript only, such as 13 C or 235 U. photo editor programs freeWebCorrect option is B) Oxygen is group 8 element, so, the atom of oxygen has 8 protons and 8 electrons. The ion has the same number of protons because you never lose a proton to make an ion. But in the case of oxide form, it carries two negative charges. Negative charge come due to the transfer of electron. Therefore the number of electrons is 10. how does ethidium bromide stain dnaWebAs such, any element with 6 protons is identified as a carbon atom regardless of how many neutrons it may have.
