What is the valence electron of Pb lead?
(Xe) 6s² 4f¹⁴ 5d¹⁰ 6p²Lead / Electron configuration
How many electron shells does PB have?
The atomic number is the number of electrons in that element. The atomic number of lead is 82. That is, the number of electrons in lead is eighty-two. Therefore, a lead atom will have two electrons in the first shell, eight in the 2nd orbit, eighteen electrons in the 3rd shell, and thirty-two in the 4th shell.

How do you determine valence electrons?
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
How many valence electrons are in an atom of p?
5 electrons The highest-numbered shell is the third shell, which has 2 electrons in the 3s subshell and 3 electrons in the 3p subshell. That gives a total of 5 electrons, so neutral phosphorus atoms have 5 valence electrons.
How many valence electrons does Pb have and what are the specific valence electrons for?
Valence electrons are electrons in the outer most shell or orbit and there are 4 valence electrons present in the lead (Pb) outermost shell.

How do you find a valence number?
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
What are the 7 valence electrons?
The family of elements having seven electrons in the valence shell is halogens, i.e., chlorine, fluorine, bromine, iodine, astatine.

What element has the valence of 7?
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
How many valence electron are there in p?
5 electrons The highest-numbered shell is the third shell, which has 2 electrons in the 3s subshell and 3 electrons in the 3p subshell. That gives a total of 5 electrons, so neutral phosphorus atoms have 5 valence electrons.
How many valence electrons are found in an atom of p?
five Phosphorus is a neutral element that belongs to Group 15A. The valence electrons in the phosphorus atom are five. These can be found at the atom's third energy level. Phosphorus may create three bonds with other elements due to its large amount of valence electrons.
How many valence electrons are in each atom?
As a general rule, a main-group element (except hydrogen or helium) tends to react to form a s2p6 electron configuration. This tendency is called the octet rule, because each bonded atom has 8 valence electrons including shared electrons.
How do you count valence electrons?
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
Which group of elements has 8 valence electrons?
group 18 Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr).

How do you find valence electrons?
Now that you know your element's electron shells, finding the valence electrons is easy: just use the number of electrons in the outermost shell. If the outer shell is full (in other words, if it has eight electrons or, for the first shell, two), the element is inert and will not react easily with other elements.
How do you calculate valence?
The ones digit in the group number is the number of valence electrons. To solve without a periodic table, find the electron configuration of the element and count the electrons into 1 group of 2, and then into shells of 8. The number in the last group is the amount of valence electrons.
What elements has 7 valence electrons?
The family of elements having seven electrons in the valence shell is halogens, i.e., chlorine, fluorine, bromine, iodine, astatine.
What is the easiest way to find valency?
The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of valence electrons, you can easily calculate the valency.

What elements has 6 valence electrons?
They are oxygen (O) , sulfur (S) , selenium (Se) , tellurium (Te) , and polonium (Po) . Note that the synthetic element livermorium (element number 116 ) is also predicted to have six valence electrons, but it's not proven yet. These elements all belong in group 16 or the chalcogens group.
