What element has 5 valence electrons and is in Period 3?

Phosphorous is the 5th element from the left in the third period so it has five valence electrons.

Simply so, what element has 7 valence electrons and is in period 5?

Answer and Explanation: Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.

Likewise, which element has 5 valence electrons on the 3rd energy level? Boron

In this way, what element in Period 4 has 5 valence electrons?

Explanation: The elements of group 15 (column) VA of the periodic table all have electron configurations of s2p3 , giving them five valence electrons. These elements include Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb) and Bismuth (Bi).

Which element in period 3 has 6 valence electrons?

Sulfur

What kind of element has more than 4 valence electrons?

Carbon has four valence electrons and here a valence of four. Each hydrogen atom has one valence electron and is univalent.

What family has 8 valence electrons?

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.

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.

Where are the valence electrons in an atom?

Answer and Explanation: The valence electrons of an atom are those in the outermost shell. Electrons are all located outside the nucleus of an atom, with protons and neutrons

What are valence electrons and why are they important?

Valence electrons are the electrons that reside in the outermost electron shell of an atom in the highest energy level. They are important to an atom because the fewer valence electrons that the atom holds, the less stable it becomes.

Which element is the most reactive?

Fluorine is identified as the most electronegative element in the periodic table, making it the strongest oxidizing agent. It is the most reactive non-metal. Fluorine is so reactive that it can burn substances that one would generally think of as non-flammable!

What are the elements in Period 5?

The period 5 transition metals are yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo), technetium (Tc), ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), and cadmium (Cd).

What is the metalloid with 7 valence electrons?

Halogens ?Group 17 nonmetals on the periodic table that contain 7 valence electrons. They only need to gain 1 valence electron to have a stable octet. They gain valence electrons the most readily, making them the most reactive nonmetals.

What Period 4 element has 6 valence electrons?

Oxygen is located in group 16 on the periodic table, so it has six valence electrons.

Which element is a row 4 noble gas?

Krypton (Kr) is a noble gas, placed under argon and over xenon.

What is the number of valence electrons in phosphorus?

five

How many valence electrons does group 14 have?

four valence electrons

Which element is a noble gas?

Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

What are valence electrons on the periodic table?

Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus. To find the number of valence electrons of an element, we must only refer to the periodic table and seek the element's position within it.

How many valence electrons does group 7 have?

The Group 5 atoms have 5 valence electrons. The Group 6 atoms have 6 valence electrons. The Group 7 atoms have 7 valence electrons.

How many valence electrons does oxygen have?

6 valence electrons

Does boron have 5 valence electrons?

Boron has a charge of 5. This is balanced by 5 electrons. Two of them are core electrons and the remaining 3 are valence electrons. The valence electrons may participate in bonding through sharing with other atoms, to make three bonds.

What element has 3 electrons in the 3rd energy level?

Element	Element Number	Number of Electrons in each Level
Helium	2
Lithium	3	1
Beryllium	4	2
Boron	5	3

What are core and valence electrons?

Valence electrons occupy the outermost shell or highest energy level of an atom while core electrons are those occupying the innermost shell or lowest energy levels. This difference greatly influences the role of the two types of electrons in a chemical reaction.
