2. 2.how many valence electrons are found in a carbon atom? there are four valence electrons
FOUR VALENCE ELECTRONS
Carbon has four valence electrons and here a valence of four. Each hydrogen atom has one valence electron and is univalent.
3. of those electrons of carbon how many are valence electrons
Answer:
An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion.
...
The number of valence electrons.
Periodic table group Valence Electrons
Group 18 (VIII or 0) (noble gases) 8**
Answer:
four valence
Atomic carbon has six electrons: two inner shell (core) electrons in the 1s orbital, and four valence (outer most shell) electrons in the 2s and 2p orbitals.
4. how many valence electrons are in the He
Answer:
Helium has two electrons in its outermost shell, so it has two valence electrons.
5. how many valence electrons in nitrogen
Answer:
5 valence electrons
Nitrogen is found to have either 3 or 5 valence electrons and lies at the top of Group 15 on the periodic table. It can have either 3 or 5 valence electrons because it can bond in the outer 2p and 2s orbitals.

9. how many valence electrons of silver
☁️Answer☁️how many valence electrons of silver? ┈──┈──┈──┈──┈──┈──┈──
Silver's atomic number is 47. If we write up silver's electron configuration, we get 2, 8, 18, 18, 1. Valence electrons are those in the outer most shell, in this case the fifth shell. As you can see, silver has 1 valence electron.
Additional note:
Silver's atomic number is 47: 2 + 8 + 18 + 18 + 1 = 47! check your calculator...
Using the 2n squared rule, the third shell should have a capacity of 18 electrons, not 8!

12. how many are the valence electrons of carbon atom?
Answer:
Four valence electrons
Explanation:
Like other group 14 elements, carbon has four valence electrons. Valence electrons are the electrons in the outer energy level of an atom that are involved in chemical bonds.
13. how many valence electrons are there in an aluminum ion?
Answer:
No valence electrons.
Explanation:
Almunium atom has three valence electrons is its valence shell.
Al (z = 13) → 2 , 8 , 3
But Almunium ion has 3+ charge on it when it losses its three valence electrons.
The Almunium ion configuration becomes :-
[tex] Al^{+3}= 2 , 8 [/tex]
hence,
It has no valence electrons.

18. how many method in determining valence electron?
Answer:
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.

22. How many valence electrons in Lithium
Valence Electrons and the Periodic Table
The number of valence electrons in an atom is reflected by its position in the periodic table of the elements Across each row, or period, of the periodic table, the number of valence electrons in groups 1–2 and 13–18 increases by one from one element to the next. Within each column, or group, of the table, all the elements have the same number of valence electrons. This explains why all the elements in the same group have very similar chemical properties.
For elements in groups 1–2 and 13–18, the number of valence electrons is easy to tell directly from the periodic table. This is illustrated in the simplified periodic table It shows just the numbers of valence electrons in each of these groups. For elements in groups 3–12, determining the number of valence electrons is more complicated.
Q: Based on both periodic tables , what are examples of elements that have just one valence electron? What are examples of elements that have eight valence electrons? How many valence electrons does oxygen (O) have?
A: Any element in group 1 has just one valence electron. Examples include hydrogen (H), lithium (Li), and sodium (Na). 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). Oxygen, like all the other elements in group 16, has six valence electrons.
Valence Electrons and ReactivityThe table salt pictured contains two elements that are so reactive they are rarely found alone in nature. Instead, they undergo chemical reactions with other elements and form compounds. Table salt is the compound named sodium chloride (NaCl). It forms when an atom of sodium (Na) gives up an electron and an atom of chlorine (Cl) accepts it. When this happens, sodium becomes a positively charged ion (Na+), and chlorine becomes a negatively charged ion (Cl-). The two ions are attracted to each and join a matrix of interlocking sodium and chloride ions, forming a crystal of salt.
