Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.
How many valence electrons is in the element boron?
Boron has 3 valence electrons.
What is the number of valence electrons the element boron?
Boron has 3 valence electrons out of five total electrons.
Which element in the 3 period has 3 valence electrons?
Aluminum, element number 13. You can tell how many valence electrons an element has by looking at its group (column). This rule only applies for the metals and nonmetals, however. In other words, columns IA, IIA, (skip the middle section starting with Sc and ending with Zn) IIIA, IVA, VA, VIA and VIIA have 1, 2, 3, 4, 5, 6 and 7 valence electrons, respectively.
Which of the representative elements in period 4 has 3 valence electrons?
The representative element in period 4 with 3 valence electrons is phosphorus.

How many valence electrons do the Group13 element have?
They have 3 valence electrons unless they are isotopes.
How can you predict and element's group and period?
Group No = No.of valence electrons in the outer configuration period No = principle quantum No.(n)of the last shell of outer configuration Eg:carbon EC=1s2 2s2 2p2 No.of valence electrons=4, indicates G.No.is IV n=2, indicates period No. is 2 chlorine EC=3s2 3p5 valence electrons=7,so G.No. is VII n=3,so period No is 3
Which element in the 3 period has 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 3A element is 3. These elements have three valence electrons because they are located in group 3A of the periodic table, which corresponds to the third column from the left.

How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
