How many valence electrons can an atom have?
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
Why do elements in a group all behave similarly?
Elements in the same group behave similarly because they all have the same number of electrons in their outer-most orbits. These electrons are what determines the types of bonds and chemical reactions the atom can undergo.
What chemical characteristics do elements in a group share?
Elements of the same group generally share the same number of valence electrons, which are the electrons in the outer energy level only. These are the electrons that participate in a chemical reaction, so elements in the same group behave similarly in chemical reactions, which makes predictions and generalizations possible.
If Compared to metals and nonmetals how do atoms of semimetals behave when combining with elements of other elements?
They can either lose or share electrons when they combine with other elements. So, depending on the conditions , these elements can behave as either metals or nonmetalss. Durr !
How many valence electrons are present in silicon?
The valency of silicon is 4. This means that this atom has the tendency to behave as if it had 4 'hooks'. Basically, silicon is ready to take on 4 electrons with which it would secure the same electronic configuration as Ar (argon) which is one of the most stable, non-reacting gases, and this is what most atoms are aiming for; a stable state.

What does the group number of an element tells us?
Elements on the periodic table in the same group have the same number of valence electrons. Since valence electrons are the only part of an atom that interacts with other atoms during a chemical reaction, you can make generalizations about elements' reactivity based upon what group they're in. Elements in the same group will behave similarly in chemical reactions even if they bear little resemblance to each other physically.
How do valence electrons of atoms behave when forming an ionic bond?
Electrons are transferred when ionic bonds are formed.

These are the electrons that participate in a chemical reaction, so elements in the same group behave similarly in chemical reactions, which makes predictions and generalizations possible.
What does the study of the periodic table have to do with classification and prediction?
The elements in the Periodic Table are arranged so that elements in the same group (column) will exhibit certain similar characteristics with others in that same group, but different periods (rows). So you can predict, with a certain degree of confidence, how a certain element may behave by where it is located on the periodic table, based on what you know about how other elements in the same group behave. This is mainly due to the valence electrons (the outermost electrons) being the same configuration as others in the same group. The valence electrons are a big determining factor as how that element will react with other elements. They do not all behave exactly the same, but similar.

How many valence shell electrons are there in semiconductor atoms?
Silicon, the most widely used semiconductor, has four valence electrons. This places it in between the conductive metals, which have one to three valence electrons, and the non-conductive non-metals which have five to eight valence electrons.

A student asserts that silicon and germanium become good insulators at very low temperatures and good conductors at very high temperatures. Do you agree?
silicon and germanium have 4 valence electrons...they will be bound by covalent bonds at very low temperature..hence there will be no delocalized electrons to conduct electricity..therefore at low temperature these two elements behave like insulators....at high temperature,the energy will be sufficient to break the covalent bond and thus electrons become delocalized....therefore at high temp they behave like conductors
What predicts an element's properties?
The answer you are probably looking for is the periodic table, which arranges the elements. The periodic table can help predict properties of an element based on the element's location. All the elements in a veritcle collum (also known as family or group) will have the same number of valence electrons and thus behave in a similar manner. Elements can also be compared to one another on the horizontal axis(the period). i.e. moving from left to right elements become less metalic and do not exibit metallic properties as stongly. General location on the table can tell you what type of element it is; metal, nonmetal, metalloid/semimetal. or the # of protons and electrons in the element, the atomic mass.
