How do the valence electron of mercury make it bonding weaks?
Mercury easily shares its valence electrons
What is true of the bonds in a water molecule?
Oxygen holds electrons more tightly than hydrogen does, and the net charge is zero
The first energy level holds how many electrons?
2 electrons
How do you account for fair and poor conductors of electricity?
The mobility of the electrons in matter. Tightly bound electrons make for poor conductors.
Generally a complete valence shell holds how many electrons.?
Generally, a compete valence shell holds EIGHT electrons.
Do some materials hold onto electrons more tightly than others when charging by rubbing to occur?
Electrons are ripped off one material and held tightly by the other material.
How friction can be used to transfer electrons?
When two materials rub together, the loosely held electrons of one material move to the material with the more tightly held electrons.
What is a conductor and a insulater?
A conductor is any material in which electrons are free to flow, whereas an insulator is any material in which the electrons are tightly bound to the molecules with which they are associated.
How can friction be useful to us?
When two materials rub together, the loosely held electrons of one material move to the material with the more tightly held electrons.
How do the valence electron of mercury make it bonding weaks?
Mercury easily shares its valence electrons
What is true of the bonds in a water molecule?
Oxygen holds electrons more tightly than hydrogen does, and the net charge is zero
How does rubbing one object on another create electricity?
the electrons get ripped off one object and held by the other The rubbing moves electrons to the object that holds them more tightly.
What is a material through which electrons do not easily flow?
insulator
What force holds inner planets tightly to the sun?
Gravity :) (Gravity also holds the outer planets tightly to the Sun.)
How many electrons can each orbitals hold?
s holds 2 electrons (e-)p holds 6 electrons (e-)d holds 10 electrons (e-)f holds 14 electrons (e-)This is true if you mean orbitals and not orbits.
Why metal are close packing?
Atoms in a metal are very closely bound with metallic bonds (shared electrons). This bond holds the particles very tightly. In mercury, the electrons are bound more tightly and resist forming these bonds, causing it to remain a liquid at fairly low temperatures (including room temperature).
Why do materials carry current?
Materials carry current because of the way the electrons of the material behave. Current is proportional to the number of electrons. If the electrons are loosely bound on the material then they are available to carry current along the material. Copper is a common metal who's configuration means that the electrons are loosely bound and as such is very good at carrying current. If on the other hand the electrons are tightly packed into the atoms in the material then they aren't available to carry current. Materials such as glass and plastic are good examples.
