there are lots of pairs on the periodic table that are both malleable and good conductors of heat , but in this case two good examples would be
- Silver (Ag) & Copper (Cu)
Valance electrons are the extra electrons on the outermost orbital, that hasn't been filled yet. For example, Lithium would have one valence electron, on the 2s orbital, because that is an extra electron floating around that 2s orbital, that can be shared with others, since each element's goal is to have no valence electrons. If an orbital is filled, it therefore has no valence electrons, because valence electrons are only extra electrons, if that makes any sense.
There are many groups of the periodic table. These groups categorize electrons by the amount of valence electrons they have. The group on the far left, the alkali metals, all have one valence electrons. The alkali metals include Lithium, Sodium, and other elements, so therefore give away that one electron easily, because if they give it away they won't have any valence electrons. (This is why you often see salt, sodium chloride, because sodium gives away its one valence electron to chloride, who needs one electron to have no valence electrons.) One other notable group is the noble gases, on the far right of the periodic table. These elements have no valence electrons, so therefore won't bond easily with other elements.
Hope this helped!

6 grams of Carbon is it’s mass
<u>Explanation:</u>
First we have to divide the given number of atoms by the Avogadro's number , so that we will get the number of moles as 1/2.
Then the 1/2 moles of carbon is multiplied by the molar mass of Carbon which is 12 g/mol, we will get the mass of carbon as 6 grams.
So the mass of the carbon obtained is 6 grams.
