Q20: Covalent and metallic bonding both involve interactions between atomic nuclei and valence electrons. ► Which of the following is a similarity between covalent and metallic bonding?
A They can link atoms into periodic
lattices.
B They are easily broken at room temperature.
c They always involve a "sea” of delocalized electrons.
D They are nondirectional.
E They can link atoms into separate molecules.
Which of the following is a difference between covalent and metallic bonding?
A Only covalent bonding can occur between atoms of different elements.
BOnly metallic bonding can involve more than one valence electron per bonded atom.
C Only metallic bonding can occur between oppositely charged ions.
D Only covalent bonding can produce materials that are electrically insulating.
E Only metallic bonding can produce materials that are electrically conductive.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
