Draw the lewis dot structure for the ion scn−. (carbon is the central atom.) how many lone pairs of electrons are in this structure? 1. four 2. none 3. eight 4. two 5. six

Using Lewis Dot Symbols to Describe Covalent Bonding Edit section. Lewis electron structures for more complex molecules and ions:If the central atom has fewer electrons than an octet, use lone pairs 5. Adding the remaining 4 electrons to the oxygen (as two lone pairs) gives the following structure:

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
