Additional Exercise 11.79 Why does carbon have a maximum of four covalent bonds? Carbon has valence...
20. How do atoms achieve noble-gas electron configurations in single covalent bonds? a. One atom completely loses two electrons to the other atom in the bond. b. Two atoms share two pairs of electrons. C. Two atoms share two electrons. d. Two atoms share one electron 21. Why do atoms share electrons in covalent bonds? a to become ions and attract each other b. to attain a noble-gas electron configuration c. to become more polar d. to increase their atomic...
Covalent bonds form between hydrogen, carbon, and oxygen atoms when valence electrons are shared between the atoms valence electrons are subsituted between the atoms electrons are attracted to the nucleus protons are shared between the atoms
Answer true or false. 1. Atoms that lose electrons to achieve a filled valence shell become cations and form ionic bonds with anions. 2. Ionic bonds tend to form between elements on the left side of the Periodic Table, and covalent bonds tend to form between elements on the right side of the Periodic Table. 3. Electronegativity is a measure of an atom's attraction for the electrons it shares in a chemical bond with another atom. 4. Fluorine, in the...
The Lewis symbol for the nitrogen atom has _______ valence electrons. The number of covalent bonds which nitrogen usually forms in order to complete its valence shell and obey the octet rule is _______. 5, 2 3, 4 5, 3 5, 4 5, 1
1. Draw the Lewis structure of water showing all valence electrons with lines for covalent bonds and dots for unshared electrons. Add a box around each hydrogen- bonding donor site and add a circle around any hydrogen- bonding acceptor sites in your structure. (Hint: there are two of each. The equal number of donors and acceptors is why water hydrogen-bonds so well with other waters.) Draw the Lewis structure of hydrofluoric acid, HF, showing all valence electrons with lines for...
how many covalent bonds does each carbon have in the Lewis structure?
Match each description with the most appropriate atom of the choices given: chlorine, sodium, or carbon. Most likely to formClosest to the right side of the Periodic Table Has 4 valence electrons Highest electronegativity Most likely to form an anion covalent bonds Lowest electronegativity Most likely to lose anMost likely to share Has 1 valence electron Has 7 valence electrons electron electrons Most likely to gain an Closest to the left side Most likely to form a of the Periodic...
8. Why does carbon contain only 4 valence electrons when it has 6 total electrons? 9.True or False. Oxygen and sulfur have the same number of valence electrons. 10. True or False. Beryllium and magnesium have the same number of valence electrons. 11. True or False. Sodium and magnesium have the same number of valence electrons. 12. What is the relationship between the number of valence electrons and the column on the periodic table? 13. How is the number of...
What are the use of Methyl isocyanate molecule in healthcare, industry, or found in a natural source and discuss the importance of this molecule. The electron configuration of an atom determines the number of electrons available to participate in bonding with another atom. One method of depicting the valence electrons that an atom has is through the Lewis structure Identify the carbon in valence electrons and the orbitals in which they reside. Explain How many unpaired electrons are present? How...
