Which sub levels contain valence electrons in the atom of argon?
Argon does not contain valence electrons.
What element has three unpaired electrons in the p sub level?
Any group 5 element
How does the periodic table indicate the number of valence electrons an element have?
By the group number of the A columns.....go apex :D
How many valence electrons does zinc have in its outer shell?
Zinc is [Ar] 3d104s2 so there are 2 valence electrons.
Why do all elements in a group have similar physical and chemical properties?
Seldom do they have similar physical properties - many of those depend on atomic mass and related properties, and they increase down the group. Chemically, they are similar mostly because their outer (valence) electronic structure is the same.
Which sub levels contain valence electrons in the atom of argon?
Argon does not contain valence electrons.
What element has 2 electrons in the 1s sub-level 2 electrons in the 2s sub-level and 2 electrons in the 2p sub-level?
Carbon
What element has three unpaired electrons in the p sub level?
Any group 5 element
How does the periodic table indicate the number of valence electrons an element have?

What number on the periodic table indicates the energy level of an atoms valence electrons?
The number beside the letter represents the energy level. The letter represents the sub level. The exponent represents the number of electrons in the sub level. So in the case of: 1s^2 1 is the energy level; S is the sub level; ^2 is the number of electrons in the sub level.
What is the number of electrons in the sub level d?
The maximum number of electrons in a 'D' sublevel is 10
How many valence electrons does zinc have in its outer shell?
Zinc is [Ar] 3d104s2 so there are 2 valence electrons.
What is the highest sub level electron occupy in uranium 238?
The highest sub level electrons occupy in a Uranium-238 atom is a f-sub level.
Does helium atom has the same number of electrons in its outer shell as in magnesium atom?
yes, both helium and magnesium have 2 valence electrons. the difference is that in helium, the 2 electrons make up an entire electron level. In Magnesium, they only make up the s orbital, or 1st electron sub-level.
Is it true that the number of valence electrons is equal to the group number?
It is true for the Alkali Metals, Alkaline Earth Metals, the Boron group, the Carbon group, the Oxygen group, the Nitrogen group, Halogens, and Noble gases. Their valence electrons are the electrons on the outer sub-shell, but Transition Metals and Rare Earth Metals don't quite follow the same pattern. For any other questions, try your science teacher! That's probably the best source you have at the moment because they know exactly what you already know.
How many electrons can 3d hold?
There are a maximum of 10 electrons in the 3d sub-level.
What element has 3 electrons and P sub level?
These would be p block elements in group 5 (XV)N, P, As, Sb, Bi
