Yes, as the strongest of the species continue to survive (which is what natural selection is all about) they can mutate causing improved features and eventually new species (note that this happens over hundreds of thousands of years.
An example is the giraffe. It evolved from a type of horse who’s neck wasn’t long enough to reach the leaves on trees. Therefore, those born with longer necks were more likely to live, and the process of natural selection helped form giraffes as we know them today.
The name of the compound is Thorium (IV) Iodide and formula of the compound ThI₄.
<h3>What is Molecular Formula ?</h3>
The chemical formula that gives total number of atoms of each element in one molecule of a compound is called Molecular Formula.
<h3>What is Atomic Number ?</h3>
The number of proton which is used to separate one element from the other element is called Atomic Number.
here the atomic of the element Q is 90 and the atomic number of R is 53. The element Q is Thorium. Symbol of Thorium is Th. The element R is Iodine. Symbol of Iodine is I.
The valency of thorium is +4 and valency of Iodine is -1. So the formula of the compound is ThI₄.
Thus from the above conclusion we can say that The name of the compound is Thorium (IV) Iodide and formula of the compound ThI₄.

Answer:
The Bohr model and all of its successors describe the properties of atomic electrons in terms of a set of allowed (possible) values. Atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states. Direct experimental evidence for the existence of such discrete states was obtained (1914) by the German-born physicists James Franck and Gustav Hertz.
