Isotopes are the atoms of the same element that have different numbers of neutrons. Like the example in the book is Boron 10 and 11. You look at the periodic table to find protons, and then use the formulia neutrons= mass #- atomic #. Then you know the amount of neutrons, which in Boron's case is 5 or 6.

Isotopes are atoms of the same element but have a different number of nuetrons in them so they are uneven and different

Isotopes are atoms of the same element, but have a different number of neutrons. An example would be Carbon-12 qnd Carbon-14. Another example would be Boron-10 and Boron-11.

They are atoms that are part of the same element that have a different ammount of neutrons. An example is Carbon-12

Isotopes are different forms of an element. They are an atom of the element that has a different number of neutrons. Therefore, the average of all the isotopes of an element = the average atomic mass.

Isotopes are atoms of the same element that have different amounts of neutrons in them. One example is carbon 12 and carbon 13.

An isotope is the atoms of the smae element that have a different number of neutrons. A sample of it could be the element boron and the bnaturally occuring ones have a mass numbber of 10 and 11.

isotopes have different numbers of neutrons of the atoms of the same element. to find it, you take mass #- atomic #. That is what an isotope is.

an isotope is any forms of an elements that have the same number of protons in the nucleus and the same atomic number but having different numbers of neutrons in the nucleus.

An isotope is an element with a different number of protons than neutrons. An example would be an element with an atomic mass of an odd number.

Isotopes are atoms of the same element that have different numbers of neutrons. To identify isotopes, you would use the formula #of neutrons= mass # - atomic #. Some examples of an isotope is Boron 10 and 11

isotopes are atoms in an element that have different neutrons. examples are carbon 12 and 14 and boron 10 and 11

the atoms of the same element that have different numbers of nuetrons is this so called thing you call a isotope. you use the peroidic table or whatever you like to call that big chart thingy to find the isotope we talk about. You would go mass#- atomic# to get this neutron #! so that was fun! YEAH!

well isotopes are atomes of the same element that have different numbers of nuetrons than protons. Like Carbon 13 and Carbon 14. There are many different isotopes out there.

An isotope is an atom that has a different amount of nuetrons to protons. This creates an atom of the same subsance but a different charge like Boron-5, or Boron-6.

an isotope is One of two or more atoms having the same atomic number but different mass numbers. an example would be Carbon 14 instead of carbon 12 because carbon 12 is in element form. Carbon 14 is an isotope of carbon.

Isotopes are atoms of the same element, but have a different number of neutrons, which makes it different. An example would be carbon 12, and carbon 14.

It is one of two or more atoms having the same atomic number. It also has a different number of nuetrons than the element. To figure out the neutrons take protons - mass#= neutrons
