Question

Write the full symbol for the isotope of oxygen having 8 neutrons.​

Answer 1

The full symbol for the isotope of oxygen with 8 neutrons is written as 16O, since oxygen has an atomic number of 8 (which is the number of protons) and the mass number is 16 when you add the 8 neutrons.

Step-by-step explanation:

To write the full symbol for an isotope of oxygen with 8 neutrons, you need to know the atomic number and mass number of the isotope. The atomic number of oxygen is 8, which represents the number of protons and is denoted by the letter 'Z'. To find the mass number (denoted by 'A'), you add the number of protons and neutrons together.

Since oxygen has 8 protons and this isotope has 8 neutrons, the mass number is 16. The full symbol for this isotope of oxygen, which includes the atomic number and the mass number, is written as 16O8, but the 8 (atomic number) is often omitted because it's redundant and understood as the element's proton number. Therefore, the symbol can be written as 16O.

Answer 2

Isotopes are forms of a chemical element that have the same atomic number but differ in mass. 16O → 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ 18O Oxygen - 18 (aka 18O → 8 protons + 10 neutrons; a “heavy” oxygen).
