Lead is malleable, so it can be pounded into flat sheets without breaking. How does the bonding within lead help to explain this
property? Metallic bonds involve valence electrons that are removed from one atom and given to another, so the pounding helps the electrons move.
Covalent bonds involve valence electrons that are shared between two metal atoms, so the bonds are strong enough to resist the pounding.
Metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded.
Covalent bonds involve valence electrons that are removed from one atom and given to another, so the pounding helps the electrons move.
The answer is Metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded. The metallic bond structure of lead forms a cubic crystal structure and the atoms can roll over one another without breaking the metallic bonds. This is especially because the p orbital electrons of lead can be delocalized and the electrons can be shared with other lead ions in the cubic structure of lead.
In metallic bonding, the valence electrons are involved in bonding with many atoms.
As a result, valence electrons dissociate within their atomic core and form a sea of electrons which helps in binding the positively charged ions.
Thus, we can conclude that the bonding within lead help to explain this property as metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded.
A computer is made up of wires which is like nerves in our body they send signals throughout our bodies and tell us what to do about a situation. The hard drive of a computer is just like our brain which is the main component of the nervous system it controls involuntary, voluntary, movement and coordination. Also, just like the keys and mouse of a computer we have sensory neurons which pick up what is around us by touch.
The two structures that will provide positive identification of a plant cell under a microscope are I think C. cell wall and chloroplast.
Explanation:
Plant cells have some cell organelles which is unique to them, these organelles are not found in animal cells. Examples of such organelles are chloroplasts, large central vacuole, cell wall, etc.
In addition, the number of valence electrons present in the elements of these groups denotes the group. The valence electrons present in their elements reflect their particular group, which is why they are termed representative elements.
Explanation: It wouldn’t be a pure substance because it has non medical properties in it along with medical. It would be a mixture because of the mix of pure and non pure. (my opinión)
