When you go down the element generally become more or less metallic?
as you go down a group the elements become more metallic. why? ionization energy decreases. ionization energy is the amount of energy needed to remove the most loosely held electrons. when electrons are lost, a metal is formed. so as you go down a group, the electrons are futher away from the nuclear pull (because the period increases). therefore, not much energy is needed to remove the electrons making it easier to loose them
How many electrons are required to completely fill the third energy level?
no. of electrons to fill an energy level = 2n2. = 2x32 = 18
What do you call the energy which is required to bond atoms together?
Covalent [the sharing of a pair of electrons] bond energy.
Does atomic radius decrease and metalic character increase from left to right on the periodic table?
Metallic character decreases as you go across any single period of the Periodic Table. This is because metals are characterized by their ability to lose electrons to form cations; the easier it is to do so, the more reactive a metal is. Non-metals are characterized by their ability to gain electrons to form anions; the easier to do so, the more reactive a non-metal is. As you go across any single period, elements gain an extra valency electron. This makes it harder and harder for those elements to lose their valency electrons, thus becoming more and more non-metallic.
What kind of bond does gold have?
Gold has metallic bonds.The electrons of the gold atoms are delocalised to form a sea of electrons. The gold atoms are held together by electrostatic forces of attraction between the negatively charged sea of electrons and the positively charged ions (the nucleus + the electrons that are not delocalised). Gold has high melting and boiling points because a lot of energy is required to overcome this strong electrostatic forces of attraction.
How do you find valency of elements?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
What term refers to the number of electrons found on the outermost energy level of an atom?
The term is 'Valency'
Does metallic bonding occur between atoms of copper or chlorine?
Metallic bonding occurs between copper atoms. Only copper is a metal and has the characteristics needed for metallic bonding. Metallic bonding occurs between atoms with low electronegativities (low tendency to attract electrons from other atoms) and low ionisation energies (little energy required to remove electrons from the atoms). The low tendency for the metallic atoms to keep their electrons allow their electrons to be shared between the atoms, which thus become cations. The cations tend to be very closely-packed; they are not repulsed by their similar positive charges, but attracted to the electrons flowing freely between the cations. Metallic bonding therefore occurs between copper atoms, which have low electronegativity and ionisation energy. Chlorine atoms have some of the highest electronegativity and ionisation energy of all elements, and thus do not exhibit metallic bonding.
What do Valence Electrons determine?
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.

The energy required to remove electrons from an atom is called?
Ionization energy

no. of electrons to fill an energy level = 2n2. = 2x32 = 18
Why do electrons form a continuous band in metallic bonding?
The metallic bond is formed of many degenerate (same energy) orbitals, but because of PAuli exclusion principle these are split by small energy differences to form a near continuum of energy levels, a band
How many electrons are required to stabilize the first energy level?
2
