Only clue the question gives is that it has a mass number is 14
-How many Protons?
-How many Neutrons?
-Determine the Atomic Number
-The isotopes name
Write the isotope name as “element name - mass number”. For example, the element with atomic number = 1 and mass number = 3 would be written as Hydrogen-3.
- Create a diagram of the isotope,adding the appropriate number of “n” and “p” for an atom with the mass number of 13.
- The nucleus and symbols can be drawn by hand

II. Isotopes Atoms of a given element all have the same number of protons and electrons, but can have different numbers of neutrons. Versions of the same element with differing numbers of neutrons are call isotopes. The symbol for an isotope is AX Where: A is the mass number (number of protons plus neutrons) Z is the atomic number (number of protons) X is the symbol for the element 2.

A Review Constants 1 Periodic Table Subm Previous Answers Correct When identifying isotopes of an atom, we look for atoms that have the same number of protons but different masses. This means that each isotope has a different number of neutrons. In an atomic symbol of an isotope, the upper left number represents the mass number (which consists of the sum of protons and neutrons in the nucleus of the atom) and the lower left number is...

Isotopes are also represented by the notation: Name-A, where Name is the name of the of the isotope. An example of this isotope notation is magnesium-26. This represents an isotope of The extremely small size of atoms...

Radioactive isotopes have unstable nuclei that slowly break apart over time. As they decay, bits of the nucleus (protons and neutrons) are emitted which can cause damage to substances and organisms that are struck by these particles. The simplest type of radiation is the Alpha particle, which is emitted by all elements whose atomic number is 84 or greater. 1. If each alpha particle has the same composition as the nucleus of a Helium atom, how many protons and neutrons...
