Multiple Choice

1. Ionic bonds always form between metals and _____.

• 1. A. Nonmetals

• B. Metals

• C. Metalloids

Explanations

Ionic bonds occur when there is a transfer of electrons from a metal atom to a nonmetal atom. Nonmetals have a higher electronegativity, meaning they have a stronger attraction for electrons compared to metals. This makes nonmetals more likely to gain electrons and form negative ions. Metals, on the other hand, have a lower electronegativity and are more likely to lose electrons and form positive ions. Therefore, ionic bonds always form between metals and nonmetals.

Multiple Choice

2. Negatively charged ions, called ____________, result from gain of electrons.

• cations
• Anion

Explanations

Negatively charged ions, called anions, result from the gain of electrons. Anions are formed when an atom or molecule gains one or more electrons, resulting in an excess of negative charge. This gain of electrons increases the overall negative charge of the ion, making it negatively charged. Cations, on the other hand, are positively charged ions that result from the loss of electrons. Therefore, in this context, the correct answer is anions.

Multiple Choice

3. Positively charged ions, called ______, result from loss of electrons.

• 1. Cations

• Anions

Explanations

Positively charged ions, called cations, are formed when an atom loses one or more electrons. This loss of electrons creates an imbalance between the positive protons in the nucleus and the negative electrons, resulting in a net positive charge. Therefore, cations are the correct answer since they are positively charged ions that are formed by the loss of electrons.

Multiple Choice

4. When an electron is added to or removed from an atom, the atom becomes a(n) _______.

• Ions

• Bond

• Nothing; it stays an atom

Explanations

When an electron is added to or removed from an atom, the atom becomes an ion. An ion is an atom that has gained or lost one or more electrons, resulting in a net positive or negative charge. This process is known as ionization.

Multiple Choice

5. How does a magnesium atom form a bond with an oxygen atom?

• 1. By giving on pair of electrons to the oxygen atom

• 1. By sharing one pair of electrons, both electrons provided by the magnesium atom

  
  

• 1. By sharing two pairs of electrons, both pairs provided by the oxygen atom

Explanations

Magnesium will transfer two electrons from itself to an oxygen atom. So that Mg and O both achieve noble gas configuration of 2, 8.

Multiple Choice

Lewis dot shows?

• 
  The total number of electrons

• Total number of protons

• Total number of neutrons

• 
  Number of electrons in highest energy shelf

Explanations

The Lewis dot structure is a way to represent the valence electrons of an atom or molecule. It shows the number of electrons in the highest energy level or shell, which is also known as the valence shell. This is important because the valence electrons are the ones involved in chemical bonding and determining the reactivity of an atom. Therefore, knowing the number of electrons in the highest energy shelf helps us understand the chemical behavior and properties of an element.

Multiple Choice

•  

  Select the formula for strontium chloride.

• 
  SrCl2

• 
  SrCl

• Sr2Cl3

• 
  SrClO2

Explanations

The correct formula for strontium chloride is SrCl2. This is because strontium is a group 2 element with a +2 charge, while chloride is a group 17 element with a -1 charge. To balance the charges, two chloride ions are needed for every strontium ion, resulting in the formula SrCl2.

Multiple Choice

Select the formula for aluminum sulfide.

• Al2(SO4)3

• 
  AlS

• Al2S3

• 
  Al3(SO3)2

Explanations

The correct formula for strontium chloride is SrCl2. This is because strontium is a group 2 element with a +2 charge, while chloride is a group 17 element with a -1 charge. To balance the charges, two chloride ions are needed for every strontium ion, resulting in the formula SrCl2.

Multiple Choice

•  

  NaCl is an example of the chemical formula of

• An ion

• A covalent compound

• 
  An ionic compound

• 
  A crystal

Explanations

NaCl is an example of an ionic compound because it is formed by the transfer of electrons between sodium (Na) and chlorine (Cl) atoms. In this compound, sodium loses one electron to become a positively charged ion (Na+), while chlorine gains one electron to become a negatively charged ion (Cl-). The opposite charges of the ions attract each other and form a stable crystal lattice structure, resulting in the formation of NaCl.
