Which element has 4 valence electrons in the p sub level?
The element that has 4 valence electrons in the p sublevel is silicon (Si). Silicon is located in group 14 of the periodic table and has an atomic number of 14. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p², where the four valence electrons are found in the 3s and 3p sublevels.
Which sub levels contain valence electrons in the atom of argon?
Argon does not contain valence electrons.
What element has 2 valence electrons in the 2 s sub level?
The element with 2 valence electrons in the 2s sublevel is beryllium (Be). It is located in Group 2 of the periodic table and has an atomic number of 4. Beryllium's electron configuration is 1s² 2s², indicating that it has two electrons in the outermost s orbital.
What sub-level contains a maximum of three pairs of electrons?
The sub-level that contains a maximum of three pairs of electrons is the p sub-level. Each p sub-level can hold a maximum of six electrons, meaning it can accommodate up to three pairs of electrons.
What element has three unpaired electrons in the p sub level?
The element with three unpaired electrons in the p sub level is phosphorus. It has a electron configuration of 1s2 2s2 2p6 3s2 3p3, with three unpaired electrons in the 3p sublevel.

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?
The element with 2 electrons in the 1s sub-level, 2 electrons in the 2s sub-level, and 2 electrons in the 2p sub-level is carbon (Atomic number: 6).
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 sub-level contains a maximum of three pairs of electrons?
The sub-level that contains a maximum of three pairs of electrons is the p sub-level. Each p sub-level can hold a maximum of six electrons, meaning it can accommodate up to three pairs of electrons.
What element has three unpaired electrons in the p sub level?
The element with three unpaired electrons in the p sub level is phosphorus. It has a electron configuration of 1s2 2s2 2p6 3s2 3p3, with three unpaired electrons in the 3p sublevel.
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
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 valence electrons does zinc have in its outer shell?
Zinc is [Ar] 3d104s2 so there are 2 valence electrons.
Which sub levels contain valence electrons in an atom of argon?
In an atom of argon (atomic number 18), the valence electrons are found in the 3s and 3p sublevels. Specifically, argon has a complete outer shell with the electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶. Therefore, the valence electrons are the two electrons in the 3s sublevel and the six electrons in the 3p sublevel, totaling eight valence electrons.
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.
