Valence Electrons in Bohr Model, EC, and Orbital Diagram

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

7

Front

What is the formula for determining valence electrons in p-block elements?

Back

v.e. = group # MINUS 10

2

Front

What does the exponent in an electron configuration represent?

Back

The exponent represents the number of electrons in that subshell, with the highest value for n indicating the valence electrons.

Front

Back

None of the options (the valence electrons are 8: 4s^2 and 3p^6).

Front

What is the significance of the highest main energy level in an orbital diagram?

Back

It indicates the valence electrons of the atom.

Front

How many valence electrons does a typical s-block element have?

Back

The number of valence electrons is equal to its group number.

Front

What is the maximum number of valence electrons an element can have?

Back

8 (for elements in group 18, the noble gases).

Front

What is the relationship between group number and valence electrons in the periodic table?

Back

For main group elements, the group number indicates the number of valence electrons.
