Question

PLEASE HELP, WILL MARK BRAINLIEST. The two boron atoms listed in the table are isotopes of boron. The two carbon atoms and the two oxygen atoms are also called isotopes. Based on the patterns in the particle compositions of these atoms, write a definition for “isotope.”

Answer 1

Don’t really know ‘bout this one, but here’s something I found.

Answer:

Isotopes are various forms of an element that have the same number of protons but a different number of neutrons. Some elements, such as carbon, potassium, and uranium, have multiple naturally-occurring isotopes. Isotopes are defined first by their element and then by the sum of the protons and neutrons present.

Carbon-12 (or 12C) contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 amu (six protons and six neutrons).

Carbon-14 (or 14C) contains six protons, eight neutrons, and six electrons; its atomic mass is 14 amu (six protons and eight neutrons).

While the mass of individual isotopes is different, their physical and chemical properties remain mostly unchanged.
