Isotopes contain a different number of neutrons.
The type of element is decided by the number of protons in it's nucleus. Number of neutrons are either equal or more than number of protons. Mass of proton and neutron is almost equal and that of electron is almost negligible as compared to both of others. As number of neutrons differ, mass of the elements also differ. Though they have 'same' chemical properties. Such atoms with different mass are called Isotopes. If the number of neutron is more, then such Isotopes are having more mass (or weight.)
The atomic mass of an element is not based solely on the mass of electrons because the majority of an atom's mass comes from protons and neutrons in the nucleus. Isotopes of an element have different numbers of neutrons, which affects their mass. When calculating the average atomic mass, isotopes are weighted based on their natural abundance; those that occur more frequently contribute more significantly to the average than rarer isotopes. This results in a weighted average that reflects the relative stability and prevalence of each isotope.
The periodic table gives you the actual weight of an element, so that if you had a sample in your laboratory and weighed it, your result would agree with (or be very close to) what the periodic table indicates. The weight of an element depends upon the relative abundance of the various isotopes of which it is composed. Each isotope has a different weight, so the weight of the element is influenced by each isotope, with the more abundant isotopes having a correspondingly greater influence.
Isotopes with a high atomic number and/or an unstable ratio of protons to neutrons are more likely to decay. Generally, isotopes further from the line of stability on the periodic table are more likely to undergo radioactive decay.
Isotopes contain a different number of neutrons.
"More heavily" is a comparative. "Most heavily" would be a superlative.

Some isotypes are more stable than others. Decay occurs because of instability in isotopes, so stable isotopes do not undergo radioactive decay.

The HTC-Dash has Wi-Fi capabilities, 5 hours of talk time, 1.3 megapixel camera, Bluetooth capabilities, and more. The phone is comparable to many others on the market. The service provider will likely be a heavily weighed deciding factor in choosing a cell phone.
