What elements has 6 valence electrons?
What elements has 6 valence electrons?
Examples include neon (Ne), argon (Ar), and krypton (Kr). Oxygen, like all the other elements in group 16, has six valence electrons.
What metalloid has 6 valence electrons and 6 shells?
Group 16: Oxygen Group They are followed by tellurium (Te) (Figure below), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive.
What metalloid has 6 electron shells?
OXYGEN FAMILY: All have 6 VALENCE ELECTRONS (electrons in the outer energy level) Oxygen, sulfur, and selenium are NONMETALS. Tellurim and polonium are METALLOIDS.
What are the 6 metalloids on the periodic table?
The term is normally applied to a group of between six and nine elements (boron, silicon, germanium, arsenic, antimony, tellurium, and possibly bismuth, polonium, astatine) found near the center of the P-block or main block of the periodic table.
Does Group 6 have 6 valence electrons?
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 15 (V) (pnictogens) | 5 |
Group 16 (VI) (chalcogens) | 6 |
Group 17 (VII) (halogens) | 7 |
Which group contains elements with two valence electrons?
A: Calcium is a group 2 element with two valence electrons.
Does Period 4 have 7 valence electrons?
Answer: The elements in this family are fluorine, chlorine, bromine, iodine, and astatine. Halogens have 7 valence electrons, which explains why they are the most active non-metals.
Which element has 4 energy levels and 7 valence electrons?
The elements in the carbon family all will have four valence electrons, the elements in the nitrogen family will have five, the elements in the oxygen family will have six, the halogens will have seven valence electrons and aside from helium, the elements in the last column – the noble gases – will all have eight …
What is the only metalloid in Period 6?
The metalloids; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step like line between metals and non-metals of the periodic table….Metalloids.

Are metalloids dull and brittle?
Metalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides.
What group of element has a valence electron of 5/6 and 7?
Like an electron in an inner shell, a valence electron has the ability to absorb or release energy in the form of a photon….The number of valence electrons.

Group 15 (V) (pnictogens) | 5 |
Group 16 (VI) (chalcogens) | 6 |
Group 17 (VII) (halogens) | 7 |
What is the relationship between group number and valence electrons?
The group number of the representative elements = the number of valence electrons.
How do metals differ in terms of how they lose / gain electrons?
How do metals and nonmetals differ in terms of how they lose/gain electrons. Metals tend to lose electrons and nonmetals tend to gain electrons. Why are most of the elements on the left and in the middle of the periodic table metals? Because most of them have 3 or less valence electrons.
Why are most metals on the left of the periodic table?
Why are most of the elements on the left and in the middle of the periodic table metals? Halogens tend to gain electrons when they react making them nonmetals. How many electrons do the halogens tend to gain?
Which is a non metal on the periodic table?
Metals Non-Metals Worksheet Identify the following as metals, nonmetals, or metalloids using the periodic table. silicon (b) fluorine
What is the electron configuration of an element?
An element has the electron configuration [Ar]4s23d104p4. Using the electron configuration and a periodic table answer the following questions. What is the element? Selenium
