Question

chemical bonds form when atoms share valence electrons or when one atom transfers one or more valence electrons to the other atom. when electron transfer occurs, one atom loses electrons, and the other atom gains electrons. atoms will share, lose, or gain electrons until their valence shells are full. metal atoms tend to lose, or give up, valence electrons when forming chemical bonds. here are the lewis dot structures of three metal atoms: k ca ·al· nonmetal atoms, with the exception of noble gases, tend to gain or share valence electrons when forming chemical bonds. here are the lewis dot structures of three nonmetal atoms: ·n· ·s· ·cl· identify the true statements. use the periodic table and the examples above to help. fluorine atoms tend to gain or share electrons when forming chemical bonds. strontium atoms tend to lose electrons when forming chemical bonds. atoms with five or more valence electrons tend to gain electrons when forming chemical bonds. sodium atoms tend to gain electrons when forming chemical bonds.

Explanation:

Step1: Identify Fluorine's nature

Fluorine is a non - metal. Non - metal atoms (except noble gases) gain or share electrons in chemical bonds. So, "Fluorine atoms tend to gain or share electrons when forming chemical bonds" is True.

Step2: Identify Strontium's nature

Strontium is a metal. Metal atoms tend to lose electrons in chemical bonds. So, "Strontium atoms tend to lose electrons when forming chemical bonds" is True.

Step3: Analyze valence - electron rule

Atoms with five or more valence electrons are non - metals (except noble gases) and tend to gain electrons to complete their valence shells. So, "Atoms with five or more valence electrons tend to gain electrons when forming chemical bonds" is True.

Step4: Identify Sodium's nature

Sodium is a metal. Metal atoms tend to lose electrons, not gain them, in chemical bonds. So, "Sodium atoms tend to gain electrons when forming chemical bonds" is False.

Answer:

Fluorine atoms tend to gain or share electrons when forming chemical bonds: True
Strontium atoms tend to lose electrons when forming chemical bonds: True
Atoms with five or more valence electrons tend to gain electrons when forming chemical bonds: True
Sodium atoms tend to gain electrons when forming chemical bonds: False
