Question

part 2: fill - in - the - blank (2 points each, 8 points total)
instructions: complete each statement using only one word.

1. an atom that is electrically charged because it has gained or lost electrons is called an
2. the ability of an atom to attract electrons when the atom is in a chemical bond is known as
3. a is an ion with a positive electrical charge.
4. electrons in an atoms outermost shell are called electrons.

part 3: electron structures (5 points each, 20 points total)

1. draw the lewis structure for: nitrogen
2. draw the lewis structure for: beryllium
3. write the electron configuration for: nitrogen
4. write the noble gas notation for: beryllium

Explanation:

• For question 25: An atom that has gained or lost electrons and is electrically charged is called an ion.
• For question 26: The ability of an atom to attract electrons in a chemical bond is known as electronegativity.
• For question 27: An ion with a positive electrical charge is called a cation.
• For question 28: Electrons in an atom's outermost shell are called valence electrons.

Answer:

1. ion
2. electronegativity
3. cation
4. valence
