The Octet Rule States -
Correct Answer
A. That the number of electrons to fill the valence shell is 8
Explanation
The Octet Rule states that the number of electrons required to fill the valence shell of an atom is 8. This rule is based on the observation that atoms tend to gain, lose, or share electrons in order to achieve a stable electron configuration similar to that of the noble gases. By filling their valence shell with 8 electrons, atoms achieve a more stable and lower energy state. This rule helps to explain the formation of chemical bonds and the stability of certain compounds.
2.
Whats the charge that holds oppositely charged atoms together?
Correct Answer
B. Ionic Bond
Explanation
An ionic bond is a type of chemical bond that holds oppositely charged atoms together. In this bond, one atom donates electrons to another atom, resulting in the formation of positively and negatively charged ions. These ions are then attracted to each other due to their opposite charges, creating a strong bond between the atoms. The answer "Ionic Bond" correctly identifies the charge that holds oppositely charged atoms together.
3.
Nonmetals gain electrons, this forms negative ions called
Correct Answer
B. Anion
Explanation
Nonmetals have a tendency to gain electrons in order to achieve a stable electron configuration. This process results in the formation of negative ions, which are called anions. Anions have a higher number of electrons than protons, giving them a net negative charge. This is in contrast to cations, which are formed when metals lose electrons and have a net positive charge. Therefore, the correct answer is anion.
4.
Ionic Bonds_________ Electrons
Correct Answer
B. Transfer
Explanation
Ionic bonds involve the transfer of electrons. In an ionic bond, one atom donates electrons to another atom, resulting in the formation of ions with opposite charges. This transfer of electrons allows the atoms to achieve a stable electron configuration, similar to that of noble gases. Therefore, the correct answer is "Transfer."
5.
Covalent Bonds________Electrons
Correct Answer
A. Share
Explanation
Covalent bonds involve the sharing of electrons between atoms. This is what allows atoms to form stable molecules. Unlike ionic bonds, where electrons are transferred from one atom to another, covalent bonds involve a mutual sharing of electrons, resulting in a stable arrangement of electrons around each atom. This sharing of electrons creates a strong bond between the atoms involved, allowing them to form molecules with specific properties.
6.
How many electrons does it take to fill the valence shell?
Correct Answer
C. 8
Explanation
The valence shell is the outermost shell of an atom, and it determines the atom's reactivity and ability to form bonds. In order for the valence shell to be completely filled, it needs a total of 8 electrons. This is known as the octet rule, which states that atoms tend to gain, lose, or share electrons in order to achieve a stable configuration with 8 electrons in the valence shell. Therefore, 8 is the correct answer.
7.
Covalent bonds share-
Correct Answer
A. Electrons
Explanation
Covalent bonds share electrons. In a covalent bond, two atoms share one or more pairs of electrons in order to achieve a stable electron configuration. This sharing of electrons allows both atoms to fill their outermost electron shells and become more stable. Protons and neutrons are not involved in the sharing of electrons in covalent bonds. Dunkin Donuts is not related to the sharing of electrons in any way.
8.
Ionic Bonds Transfer-
Correct Answer
C. Electrons
Explanation
Ionic bonds involve the transfer of electrons. In an ionic bond, one atom donates electrons to another atom, resulting in the formation of positively and negatively charged ions. This transfer of electrons allows the atoms to achieve a stable electron configuration, similar to that of a noble gas. The attraction between the oppositely charged ions then holds the atoms together in a bond. Therefore, the correct answer is electrons.
9.
Ionic Bonds, bond two________
Correct Answer
A. Ions
Explanation
Ionic bonds occur when two ions, which are charged particles, are attracted to each other due to their opposite charges. In this case, the correct answer is "ions" because ionic bonds specifically involve the bonding of ions. The other options, such as computers, Spanish projects, and electrons, are unrelated to the formation of ionic bonds.
