Answer and explanation:
On a flat, smooth surface, such as a flat mirror, all rays that strike the same direction will be reflected at the same angle.
Parallel rays that fall on a flat surface will remain parallel after reflection. The reflection on these smooth surfaces is called specular reflection.
When the surface is irregular, such as a curved or rough surface, the rays that appear at different positions on the surface arrive at different angles of incidence, because there are normal changes along the surface.
The angle of reflection remains the same as that of incidence, but they are reflected at different angles for those looking at the surface. This type of reflection is called diffuse reflection.
6. You must divide the mass by it’s molar mass to give you the total amount of moles within that piece. This will give you approx 0.05mol. You can now multiply this value by Avagadros constant which gives you 2.93 x 10^22 atoms. I would expect gold to have less atoms as it’s molar mass is higher than that of silvers, meaning that less atoms would be required to equal the same mass
It is the electron sharing.
electronegative element + electronegative element
exemple :
O₂ , H₂
hope this helps!
Answer:
The periodic table is a table displaying each element and information about the elements, for example atomic number and chemical properties. This is necessary because without it it would be very hard to find information on the elements.
