Consider neutral atom which has 11 protons and 12 neutrons in the nucleus. The atomic number of the element is 11. The mass number for this atom is 23. The number of electrons is 11. The name of element is sodium which has symbol Na.

Particles in solids and liquids are close to each other in a sample causing solids and liquids to have definite volume and being compressible.

Element is the simplest type of matter – it cannot be broken down to any simpler substances.

Use l’Hospital’s rule, if applicable, to find the limit.

Solve the problem.Find two numbers x and y such that their sum is 420 and x2y is maximized.

Solve the problem.A local office supply store has an annual demand for 40,000 cases of photocopier paper per year. It costs per year to store a case of photocopier paper, and it costs to place an order. Find the optimum number of cases of photocopier paper per order. Hint: Use formula from the critical point theorem.
