Answer:
The answers to your questions are below:
Explanation:
Question 31 Silicon and sulphur, because they are in the same period (3)
Question 34 the third option, density is not in the table
Question 37 group 1A alkali metals
Question 38 group 1A, oxygen group
Question 39 They are metalloids
Basically all of the elements found in Group I of the periodic table also have this property. The ability to easily give up a single valence electron.
Find the pH using the concentration of hydrogen ions [H+] of 0.001M (molarity) by taking the negative log of the value:
-log[H+]=pH
-log[0.001] = pH
-log[1x10^-3]=pH
3=pH
Answer:
B
Explanation:
As you move down the periodic table in the carbon family, the atomic radius and ionic radius increase while electronegativity and ionization energy decrease. Atom size increases moving down the group because an additional electron shell is added.
