== == 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 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 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 does Flerovium have?
You can determine the valence electrons in a element by its group number. Like in group 1 those elements in group 1 have only 1 valence electron. group 2 same thing, but we skip the other groups and go straight to group 13. Group 13 would 3 valence electrons same with 14= 4 ,15= 5 ,16= 6 ,17= 7 ,18=8. So the answer to your question is Flerovium has 4 valance electrons since it is in group 14.
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)
Which of these elements has three valence electrons?
all the elements in 3A group have three valance electrons.Elements of group IIIA have three valence electrons: B, Al, Ga, etc. form 3+ charged ions.The group 13 elements all have 3 valence electrons. This group has previously been known as the earth metals and the triels. The elements in this group include boron, aluminum, gallium, indium, thallium, and ununtrium.
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.
How many valence electrons are in sillicon?
3 e-, because it is in group 13

How does group number tell you the aout of valence electrons?
The group number tells you how many valence electrons there are, except for transition metals, lanthanides, and actinides. So, for groups 1 and 2 , there are 1 and 2 valence electrons, respectively. Then it gets a little tricky. You skip to group 13, past the transition metals. What to do? You can't have 13 valence electrons. What you do is you use only the ones digit. Thus, metals in group 13 would have 3 valence electrons. The reason that the group number tells you the number of electrons is that that is the way that Dmitri Mendeleev ( the founder of the periodic table) set it up. Good Luck!
What are the valence electron of an atom?
The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet of valence electrons.

Does group 13 elements lose or gain valence electrons?
It is going to lose electrons
How many valence electrons does Flerovium have?

Like in group 1 those elements in group 1 have only 1 valence electron. group 2 same thing, but we skip the other groups and go straight to group 13.

How many valence electrons does an atom have from group 16?
Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
What can you use to ditermine the number of valence electrons of an element in the s block and p block?
For the group 1 and 2 elements, the group number is the number of valence electrons. For groups 13 - 18, subtract 10 from the group number to get the number of valence electrons.
How many valence electrons does group 18 elements have?
It has 8. It just depends on the group, like group 1 has 1 valence electron, and so on, but it doesn't count for metals, so when you get to group 2, skip the metals and go to group 13 which has 13 valence electrons. There's a pattern.
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)
