ionic bond - correct answer Between metal & nonmetal Ceramics have high bond energies covalent bonds - correct answer Between non metallic elements Processing affects structure - correct answer Structure affects properties Crystalline structures - correct answer Periodic arrangement of atoms/ions over large atomic distances amorphous - correct answer No long range atomic order Atomic bonding is metallic - correct answer It's non directional so no restrictions on # and position of nearest ...

Anatomy - correct answer The study of body structure Physiology - correct answer The study of body function microscopic - correct answer the study of structures that can only be seen through a microscope or magnification device microscopic : cytology - correct answer the study of cells and their intern...

Abiotic - correct answer Non-living Ex. A rock crystal can "grow" in a simple fashion. But rock crystals don't sense or respond to changing environments thus they aren't alive. Biotic - correct answer living - Be made of materials organized in hierarchical patterns. - Use energy and raw materials to survive. - Sense and respond to changing environments also to maintain homeostasis. - Grow, d...

Covalent bond - Ans .A chemical bond that involves sharing a pair of electrons between atoms in a molecule, the positive nuclei attracts the negative charge of the bonding pair of electrons Bonding pair - Ans .a pair of electrons shared between two atoms Metallic bonding - Ans .a bond formed by the attraction between positively charged metal ions and the delocalised electrons around them Ionic bonding - Ans .the electrostatic attraction between the cation and the anion hold the compound...
