Radioactive isotopes have excess electrons?
No (this is valid for neutral atoms); anions have excess electrons.
Isotopes with unstable nuclei are?
Unstable Isotopes will degrade through radioactive decay into other types of atoms. To break it down Unstable isotopes are those whose moleules break down to form new atoms and ions.
How many isotopes does ruthenium have?
A regular ruthenium atom has 44 electrons. But there are forms of atoms called ions, which have 1 or more extra or less electrons.
Where do radioactive atoms start on the periodic table?
After lead, all elements on the periodic table have only radioactive isotopes.
What is meant by half life of radioactive isotopes?
This is the time in which half the the atoms was disintegrated.
Do isotopes contain more electrons than other Atoms?
No, they contain different number of electrons. Isotopes differ in their number of neutrons.
What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
How do the atoms of one isotope differ from those of other isotopes of the same element?
Primarily, isotopes differ in the number of neutrons in the nucleus. Secondarily, because some combinations of protons and neutrons produce an unstable nucleus, they may differ by being radioactive.
State what is meant by half life of radioactive isotopes?
This is the time in which half the the atoms was disintegrated.
What are 3 positive things that radioactive atoms can be used for?
- radiodiagnostic- treatment with isotopes- isotopes as tracers- sources of energyand many other
Do isotopes exist because atoms of the same element can have different numbers of electrons?
Isotopes have the same number of protons an electrons; the number of neutrons is different.
What does isotopes?
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
