Question

1. use a periodic table to choose the best answer.

what is the process of losing or gaining electrons to create an ion?
ionization energy
atomic radius
ionization
electrostatic attraction

1. use a periodic table to choose the best answer.

which of the following period 4 elements would be most likely to lose electrons to form a cation?
br
kr
k
ge

Explanation:

• Question 7: Ionization is the process of losing or gaining electrons to form an ion. Ionization energy is the energy required to remove an electron from an atom. Atomic radius is the size of an atom. Electrostatic attraction is the force between charged particles.
• Question 8: Potassium (K) is a metal in period 4. Metals tend to lose electrons to form cations. Bromine (Br) is a non - metal and tends to gain electrons. Krypton (Kr) is a noble gas and is very stable. Germanium (Ge) is a metalloid and has less tendency to lose electrons compared to K.

Answer:

1. Ionization
2. K
