How many valance electrons does boron have?
im not sure but i thinks it's three
How many electrons magnesium have?
Magnesium is a metal element. There are 12 electrons in a single atom.
How many dots should you draw in the Lewis structure for carbon C?
im almost positive that you would use 10 electrons. carbon has 4 valence electrons but since you have to that makes eight, and then of course the 1 valence for each of the hydrogen atoms, 2, so that gives you ten
How many valence electrons does sodium electrons?
Only 1, It's has 3 Energy Levels and only one Electron in it's outermost level.Sodium has 1 Valence Electrons. remember that in each group 1,2, 13, 14, 15, 16, 17, and 18 every element has the same Valence electrons in each group. Like Group 1 they all have 1 valence electrons. Group 2 has 2, Group 13 has 3, Group 14 all have 4, Group 15 all have 5, Group 16 all have 6, Group 17 all have 7, and finally Group 18 all have 8 valence electrons. the other groups have zero Valence electrons. Got to Touchspin on Google and theres a Periodic Table that has the valence electrons for everything. On the side of the webpage its the second button that has the table.sodium has 8 valence electrons hint. the number of valence electrons is equal to the group number the element is in1,2, or 7 im not sureEdit: the answer is 1 electron in the valence shell, with a valence of 7Just like the rest of the alkali metals, sodium has one valence electron. This is why sodium is so reactive and has a low ionization energy--it is "eager" to get rid of this valence electron to fulfill the octet rule.See links/related questions below.Sodium has 1 valence election, just like all it's friends in the 1A group. Hope this helps!
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.
What is sharing of atoms in the outer energy levels of two atoms?
the creation of an ionic compound. the two come together to form a new molecule.

How many protons and electrons are there in the Chromium VI?
Chromium is a transition metal and his varying valences and properties compared to normal non transition metals. All elements of the same type have the same number of protons, its what makes them their particular element. So chromium isotopes, allotropes etc will always have 24 protons. Electrons though im not sure i know that in say iron (II) and iron (III) it means that iron has a valence of 2 and 3 and hence an ionic charge of of 2+ and 3+ when it gives up the outer shell electrons corresponding with the roman numeral. im pretty sure that chromium VI means it has 6 electrons in its outermost valence shell. which is weird for a metal though as they usually don't have more than 4 electrons in their outer shell so im not sure. hopefully that's helpful.
How many electrons does one atom of chromium have?
the answer is 24 electrons and yes im only 14 yrs old again
How many lone pairs of electrons are in XeOF4?
XeOF4 has four lone pairs of electrons. This molecule has a total of 36 valence electrons, 28 of which are used to form bonds with the surrounding atoms (oxygen and fluorine), while the remaining 8 electrons are not involved in bonding and are considered lone pairs on the xenon atom.
What element has two 2s electrons?
Actually the atomic number tells you how many protons there are. And there are 6 elements with 2 electrons. You can find out that out by looking at a periodic table and looking at family 2. Im guessing you won't be able to find the element your looking for unless you know the number of nuetrons or even better the number of protons.
Is sulfur a mineral igneous sediment or metamorphic rock?
im not really sure if u can eat sulfur but i know its a mineral
