This quiz explores key concepts in chemical bonding, focusing on covalent and ionic bonds, electronegativity, and electron configurations. It assesses understanding through questions on molecular stability, valence electrons, and atomic characteristics, making it relevant for learners studying advanced chemistry.
Electrons in the outer cloud of an atom
A negatively charge ion
A positively charge ion
Ionically bonded electrons
Rate this question:
The H2 symbol represents two atoms of Hydrogen.
The H2 symbol represents a Hydrogen atom.
The H2 symbol represents a water molecule.
The H2 symbol represents an ionic bond.
Rate this question:
Hydrogen has an atomic number of one and is unsatisfied when the outermost orbital is unfilled. A hydrogen molecule of two hydrogen atoms is more stable than two individual hydrogen atoms
Hydrogen has an atomic number of two and does not need to share
Hydrogen usually combines with other atoms to form covalent bonds
Hydrogen has one proton and is in search of one neutron
Rate this question:
The strong electron attraction that causes the pairing of a loss and a gain is the ionic bond. Sodium (Na) has 11 electrons with 1 valance electron. Chlorine (Cl) has 17 electrons with 7 in its valence outer orbit. If Sodium looses its valance electron, its next shell will be full (with 8 electrons). That would make Sodium a positive ion. If Chlorine gains that 1 valance electron, its shell would be full with a maximum of 8 electrons, and it would then be a negative ion.
The uneven electron attraction that causes the pairing of a loss and a gain is the ionic bond. Sodium (Na) has 17 electrons with 7 in its outer orbit. Chlorine has 11 electrons with 1 valance electron. If Sodium gains one electron it fills it’s valance and is a negative ion. If Chlorine looses 1 electron to Sodium, its next shell is full with 8 electrons and it becomes a positive ion.
The attraction balance of electrons causes ionic bonding. Sodium (Na) has 8 electrons with 6 in its outer orbit. Chlorine has 12 electrons with 2 in its outer orbit. If Sodium gains two electrons it fills it’s valance and is a negative ion. If Chlorine looses 2 electrons to Sodium, it's next shell is full with 8 electrons and becomes a positive ion.
An ionic bond occurs whenever an atom with s low electronegativity pairs with an atom of a higher electronegativity. Sodium has a strong electronegativity and Chlorine does not, so they can form an ionic bond.
An ion is an atom that has been charged due to the loss or gain of electrons.
An ion is an electronegative charge.
An ion is a positively or negatively charged atom.
An ion is a neutral atom.
Rate this question:
How many electrons are in a valence.
The strength of an atoms' electrons.
The electrical charge of a polar molecule.
The exchange of electrons in ionic bonding.
Rate this question:
Hydrogen bonds are non-polar because electrons in the bonds between identical atoms (H-H) are shared uniformly. This means electrons spend equal amounts of time around each atomic center.
Hydrogen bonds are non-polar because protons in the bonds between identical atoms (H-H) are shared uniformly. This means electrons spend equal amounts of time around each atomic center.
Hydrogen bonds are non-polar because protons in the bonds between identical atoms (H-H) are not shared uniformly. This means electrons do not spend equal amounts of time around each atomic center.
Hydrogen bonds are non-polar because protons and electrons in the atom of identical atoms (H-H) are shared uniformly. This means electrons do not spend equal amounts of time around each atomic center.
Rate this question:
The number of protons and the number of electrons in an atom are always equal.
The number of protons is always greater than the number of electrons in an atom.
The number of protons is always less than the number of electrons in an atom.
The number of protons and electrons equals the mass of an atom.
Rate this question:
The e- represents the covalent Hydrogen electrons in this Hydrogen molecule.
The pair of e- represents the double covalent Hydrogen electrons in the Hydrogen molecule.
The pair of e- represents the ionic Hydrogen electrons in this Hydrogen molecule.
The e- represents the single shared Hydrogen electron in this Hydrogen molecule.
