What is the only particle that can change in number for an isotope?
The Neutron- An element with the same number of protons and electrons, but with a different number of neutrons per atom than the original element is called an "isotope". An isotope will have, for all intensive purposes, about the same chemical and physical properties as the original element. Isotopes are written as the element, followed by a dash, then the number of neutrons in one atom of that isotope (Carbon-13 is an isotope of carbon with 13 neutrons per atom)
Which subatomic particle causes the masses to be different?
Every subatomic particle has mass, so every particle will cause a slight mass change. However, in an isotope, the mass change between the parent and daughter is caused by a change in the number of neutrons.
How many neutrons does the element Al have?
14 neutrons for Al-27 isotope.
What element has the atomic number of 45?
Se-78 isotope will have 44 neutrons Br-79 isotopes will have 44 neutrons
What element is in period 5 and is a transition element and has 51 neutrons?
The isotope of zirconim, 91Zr, has 51 neutrons. In order to solve this problem, one must know that an element's atomic weight is the average of its number of protons and neutrons (only neutrons are variable). Since the atomic number is the number of protons, the atomic number subtracted from the atomic weight gives the number of neutrons. An element in period 5 that has this many neutrons is found to be zirconium (the isotope 91Zr).
What atomic particle determines the isotope of an element?
The number of neutrons.
What particle changes is required to make an element an isotope?
neutrons
Which particle is used to identify isotopes of an element?
An element alwys has the same number of electrons and protons no matter what the isotope - so the answer is the neutrons determine the isotope.

Which particle most affects which group an element is in?
Try "the proton" (change the electrons and you get ions, change the neutrons and you get an isotope.)
Which subatomic particle causes the masses to be different?
Every subatomic particle has mass, so every particle will cause a slight mass change. However, in an isotope, the mass change between the parent and daughter is caused by a change in the number of neutrons.
What subatomic particle is the MOST important when trying to figure out what the element is?
The number of protons tells you which chemical element the atom is. The number of neutrons determines the isotope of the element.
Which subatomic particle identifies an isotope?
The number of neutrons is different for each isotope.
What is an isotope of the element with 20 protons and 20 neutrons?
Yes, the isotope potassium-39 has 20 neutrons.
What transition element has 50 neutrons?
Isotope 89Y and isotope 90Zr has 50 neutrons.
What does the isotope of an element have?
An isotope of an element has a different number of Neutrons to the original element it came from. EG: Carbon( 11 neurtons) can go to carbon(12 Neutrons(
What particle is involved most in the formation of an isotope?
In isotopes of a particular element, the number of neutrons differ where the number of protons and electrons remain same.
