What atoms need only 2 valence electrons to have a filled outer level?
Those in group VI such as O, S, Se, Te, Po Lv.
How do you know that potassium an alkali metal is highly reactive is it a. its conducts heat b. it is soft and shiny metal c. it conducts electriciy d. it has one valence electron?
d is the answer. Just one valence electron- all te other characteristics are shared with oter metals.
What is the valence level for He?
Zero valence
Does aluminium have valence of -5?

Valence electrons
How many valence electrons in Te?
Tellurium (Te) has six valence electrons.
Which pair of atoms will have the same valence-shell electron configuration Se and Te Sr and Cs N and O H and He?
Se and Te will have the same valence-shell electron configuration as they are both in the same group (group 16) and have 6 valence electrons. Sr and Cs will have different valence-shell electron configurations as Sr is in group 2 with 2 valence electrons and Cs is in group 1 with 1 valence electron. N and O will have different valence-shell electron configurations as N has 5 valence electrons while O has 6. H and He will have different valence-shell electron configurations as H has 1 valence electron and He has 2.
What is the Lewis dot structure for h2te?
H-Te-H. Just add 3 lone pairs and you will have it.
What atoms need only 2 valence electrons to have a filled outer level?
Those in group VI such as O, S, Se, Te, Po Lv.
Which atoms have six valence electrons in their valence shell?
The atoms with six valence electrons are the elements of group sixteen. This list includes O, S, Te, Se, and Po. If you would like to answer this yourself, just remember that the last digit of the group number is typically the number of valence electrons that you will have. The exceptions of course are the transitional metals from group 3 to 12 and the lanthanides and actinides like uranium and plutonium. These have 2 valence electrons.

d is the answer. Just one valence electron- all te other characteristics are shared with oter metals.
How many covalent bonds does Te form?
Tellurium (Te) typically forms two covalent bonds due to its electronic configuration. It has six valence electrons, and it needs two more electrons to complete its octet. This results in the formation of two covalent bonds with other elements.
How many valence electrons are in an atom of aluminium?
There are 3 valence electrons in an atom of aluminium.
What is another name for outermost electrons?
Electrons in the outermost shell are valence electrons!
What is the valence level for He?
Zero valence
How many the valence electron of xenon?
There are no valence electrons.
Does aluminium have valence of -5?
The valence of aluminium is 3+.
