Why do elements as a family or group share similar properties?
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
How do you find the number of valence elections?
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
Does the amount of protons an element has affect chemical bonding?
Yes and no; the number of protons determine the valance number of electrons. The valence level of electrons and how full/empty it is largely determines an elements chemical behavior. I would say that valence electrons are the main determinant, but that is predetermined by protons.
How can you determined the number of valance electrons by looking at the periodic table?
Elements are located on the periodic table based off of their atomic number, but the vertical columns they are in (groups) show how many valence electrons they have. If an element were in Group 3 of the periodic table, it would have 3 valence electrons, and so on. This doesn't apply to the Transition Metals, so one should skip straight to Group 14, where the elements all have 4 valence electrons. Group 15 has 5, Group 16, 6, etc. The one exception to this is Helium, which is in Group 18 but only has 2.
Why do groups among the main -group elements display similar chemical behavior?
The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.

Carbon has six electrons in its valence shell True or False?
The number of valence electrons equals an atoms main group number. Carbon is in group 4, therefore carbon has 4 valence electrons.
What information does the column number provide on the periodic table?
For main group elements the column number is a concrete indication of then number of valence electrons (and therefore oxidation number). And since it tells you the number of valence electrons you can get a substantially reliable idea of how reactive the element is
What is the valence electron configuration for group 6a?
The elements in group 6a (16) have six valence electrons. The valence electron configuration is Xs2Xp4 , where X is the main energy level (period number).
The group number on the periodic table corresponds to which characteristic of the elements of that group?
use your brain.
What is the main reason so many molecules are made from carbon atoms?
Because , Carbon has 4 valence electrons , which is the best number of valence electrons , because it can easily give or take or share that number . . (: ~ Hope this heelps . <3
How can the number of core electrons be determine from the periodic table?
By finding the atomic number minus the group number

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.
How do you count the valence electrons of an atom?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
What is the relationship between the group and the number of valence electrons in periodic table?
They are the same! Elements in group IA (alkali metals) have 1 valence electrons. Elements in group IIA (alkaline earth metals) have 2 valence electrons. Group IIIA (boron family) has 3 valence electrons, and so on.
