Total Electrons = Outer Electrons + Inner Electrons

Front

What is the formula to calculate total electrons in an atom?

Back

Total Electrons = Outer Electrons + Inner Electrons

Front

What are valence electrons?

Back

Valence electrons are the outermost electrons in an atom that are involved in chemical bonding.

Front

How many valence electrons do noble gases have, except for Helium?

Back

8 valence electrons.

Front

Which element has the highest total electrons among the following: Aluminum (Al), Americium (Am), Arsenic (As), Astatine (At), Gold (Au)?

Back

Americium (Am)

Front

What is the significance of inner electrons in an atom?

Back

Inner electrons shield the outer electrons from the full charge of the nucleus, affecting the atom's reactivity.

Front

What is the relationship between group number and valence electrons for main group elements?

Back

For main group elements, the number of valence electrons is typically equal to the group number.

Front

Which noble gas does not follow the formula v.e. = Group # - 10?

Back

Helium (He)

Front

How many inner electrons does Calcium (Ca) have?

Back

Calcium (Ca) has 18 inner electrons.

Front

What is the total number of electrons in Gold (Au)?

Back

Gold (Au) has 79 total electrons.

Front

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

Back
