Energy of third ionisation. Look over the flow chart and notes from today to review the concepts.
Again it introduces a new concept radioactive decay.
Chart of all arsenic isotopes. Thus different isotopes of a given element all have the same number of electrons and share a similar electronic structure. Because the chemical behavior of an atom is largely determined by its electronic structure different isotopes exhibit nearly identical chemical behavior. The main exception to this is the kinetic isotope effect.
Due to their larger masses heavier isotopes tend to react. Electronic shell Ar 3d 10 4s 2 4p 3. Energy of first ionisation.

Arsenic appears in three allotropic forms. Yellow black and grey. The stable form is a silver-gray brittle crystalline solid.
Uranium is weakly radioactive because all isotopes of uranium are unstable with half-lives varying between 159200 years and 45 billion years. Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70 higher than that of lead and slightly lower than that of gold or tungsten.

Argon was suspected to be present in air by Henry Cavendish in 1785 but wasnt discovered until 1894 by Lord Rayleigh and Sir William Ramsay. Argon is the third noble gas in. Of the first 82 elements in the periodic table 80 have isotopes considered to be stable.
The 83rd element bismuth was traditionally regarded as having the heaviest stable isotope bismuth-209 but in 2003 researchers in Orsay France measured the half-life of 209 Bi to be 19 10 19 years.

These elements all line up in the eighteenth or last column of the periodic table. They all have a full outer shell of electrons making them very stable they tend not to react with other elements. Another example is the alkali metals which all align on the left-most column.
They are all very similar in that they have only 1 electron in their outer shell and are very reactive. You can see. Look over the flow chart and notes from today to review the concepts.
Read more about isotopes. Again it introduces a new concept radioactive decay. Just be aware that some isotopes are unstable and give off protons making a totally new element with another element or particle released.
Remember that when the atomic number changes it becomes an entirely new element.
