From among the subatomic particles available, we determine which element is presented by using the number of protons. The 49th element in the periodic table is Indium (In). The chemical symbol is In-62. 62 is the number representing the number of neutrons .
Answer: In-62
k=.240/(.4)^2=1.5 assuming [A]2 means [A] squared
Answer:
A lot
Explanation:
- As you go down a group, the elements get larger in size
- All of the elements of the same group have the same # of valence electrons
- As you go to the right of a period, the # of electrons in the outermost shell increases
- The elements at the top right of the table have the highest electronegativity
- Groups 13 through 17 are nonmetals
- The last group contains noble gases
etc.
