An IC or integrated circuit consists of a chip ("die") and plastic or ceramic packaging to protect the die from mechanical and (some) electrical damage. An IC with more than one die is usually called a "hybrid" IC. A "monolithic" IC is just a plain old one-die IC, but it implies that functions from a number of ICs have been incorporated into that one IC. One form of monolithic IC is where the functions of a powerful graphics processor is put on the same die as a CPU. An SOC ("System On a Chip") is another trend in monolithic ICs. "Monolithic" is something of a transitional term. Floating point, memory management, and processing units all used to to be on separate ICs. Now they are all on the same IC, but we don't call them "monolithic" any more.
For an IC chip
Simple case: First pin to the LEFT of a dot and/or a notch is pin 1. Chip with > 1 dot: The darker/deeper dot is the main dot, first pin to the left is pin 1. No dot or notch, just a semi circle on 1 side: First pin on the left is pin 1.

IC pins are numbered anti-clockwise around the IC starting near the notch or dot.
It is an opamp chip consisting of 8 pins
The hard black dot on circuit boards is a drop of epoxy placed over small integrated circuit chips. The epoxy is specially formulated to draw heat away from the IC and is essentially a tiny heat sync for the chip.

read the datasheet or databook entry for the chip. there is no other reliable way.
