In a face centered cubic structure, every atom has 12 neighbors. which arrangement of balls serves as the best model for this structure? a) 8 balls at the corners of a cube, 6 balls in the centers of the cubes faces. b) 8 balls at the corners of a cube. c) 8 balls at the corners of a cube, and one ball in the center of the cube. d) 12 balls arranged equally apart from eachother around a circle.

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
