How many valence electrons does group 13 have?
== == It is three, the valence electrons basically depends on the last number of the group its in; such as, group 14 the valence electrons would be 4. i hope i helped
How many valence electrons are in boron?
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
Which number tells you the number of valence electrons?
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
How many valence electrons are in an atom of aluminium?
3 valence electrons.
How many electrons does Ba has?
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
How many valence electrons does group 13 have?

How many valence electrons do the boron group have?
Boron is located in group 3A. It is group 13 in modern notation. This set of elements have three valence electrons.Boron is in the 13th group in the periodic table. Elements in this group has 3 electrons in the outermost energy level. That means they have 3 valence electrons.
What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
How many valence electrons are in boron?
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.

The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
What is one property that is specific to each of the groups on the periodic table?
The number of valence electrons is unique to each group. For example, group 1 has 1 valence electron, and group 3 has 3 valence electrons, and group 7 has 7 valence electrons. This is unique for each group as no other group has that same number of valence electrons.
How many valence electrons are in an atom of aluminium?
3 valence electrons.

How many valenced electrons does B have?
B (Boron) has 3 valence electrons; note that it is in group 3A.
How many valence electrons are there in the outer boron?
Boron family is group IIIA so 3 electrons are in the outermost shell.
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 many valence electrons are in sillicon?
3 e-, because it is in group 13
