Quantum Numbers
The distribution of electron density in an atom is defined by Quantum numbers. They are derived from the mathematical solution of Schrodinger’s equation in the hydrogen atom. The four types of quantum numbers are the principal quantum number (
Principal Quantum Number (
The size of an orbital and the energy of an electron are specified by the principal quantum number (
Angular Momentum Quantum Number (
The shape of the atomic orbital is given by the angular momentum quantum number (
Magnetic Quantum Number (
The orientation of the orbital in space is given the magnetic quantum number (
There is one possible
There are three
There are five
There are seven

- An electric current of 304.0 mA transports 1.00 kC of charge. Calculate the time this took. Be sure your answer has the correct unit symbol and 3 significant digits. 0 x10 ロ・ロ・ X 3 5arrow_forwardThe legal limit for chromium in drinking water is 0.10 ppm. What is the maximum permissible mass of chromium (in \mu gμg) in exactly 1.0 cup (8.0 fl. oz.) of drinking water? Assume the density of drinking water is 1.00 g/mL. (1 fl. oz. = 29.57 mL)(Express your answer with two significant digits.)arrow_forwardCHEMISTRY 3A---WORKSHEET 2 CHAPTERS 1 AND 8 1. The different colors of light have different wavelengths. The human eye is most sensitive to light whose wavelength is 555 nm (greenish-yellow). What is this wavelength in millimeters? A tun consists of four hogsheads, one hogshead is 0.500 butt, and one butt is 126 gal. How many liters are equal to 1.00 tun? 2. A day on Jupiter is 3.543 x 104 seconds long. How many earth days are equal to one day on Jupiter? 3. 4. The human body is 0.0040% iron. How many milligrams of iron does a 165 pound person contain?arrow_forward

Be sure your answer has the correct unit symbol and 3 significant digits. x10 ロ・ロ・ X H 010 Śarrow_forwardOf the flasks or laboratory instruments that are given, express their function (specify -if they can be used to measure- if their measurements are approximate or relatively exact) Erlenmeyer flask beaker burettearrow_forwardAs part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the ears passing through this intersection for a 24-hr period during a weekday. The graph of hourly traffic looks like this. a. At what time(s) does the highest number of cars pass through die intersection? b. At what time(s) does the lowest number of cars pass through die intersection? c. Briefly describe the trend in numbers of cars over the course of die day. d. Provide a hypothesis explaining the trend in numbers of cars over the course of the day. e. Provide a possible experiment that could test your hypothesis.arrow_forward
- Which of these statements are qualitative? Which are quantitative? Explain your choice in each case. (a) Sodium is a silvery-white metal. (b) Aluminum melts at 660 C. (c) Carbon makes up about 23% of the human body by mass. (d) Pure carbon occurs in different forms: graphite, diamond, and fullerenes.arrow_forwardDraw a nanoscale representation and a symbolic representation for melting copper. Describe the macroscale properties of solid copper and liquid copper.arrow_forwardIn Active Example 3-29 you calculated that you would have to work six weeks to earn enough money to buy a 1082.49 television. You would be working five shifts of four hours each at 9.25/hr. But, alas, when you received your first pay check, you found that exactly 23 of your earnings had been withheld for social security, federal and state income taxes, and workers compensation insurance. Taking these into account, how many weeks will it take to earn the 1082.49?arrow_forward
- Using Table 1.1, but without using your calculator, decide which has the larger mass: 20. mL butane or 20. mL bromobenzene 10. mL benzene or 1.0 mL gold 0.732 mL copper or 0.732 mL leadarrow_forward2.95 Engineers who design bicycle frames are familiar with the densities of aluminium (2.699 g/cm3), steel (7.87 g/cm3), and titanium (4.507 g/cm3). How does this information compare with Figure 2.12, and what would it suggest for changes in this figure if more shades were used for the density colour-coding? (Iron is the principal component of steel)arrow_forwardMarie Curie was born in Poland but studied and carried out her research in Paris. In 1903, she shared the Nobel Prize in Physics with H. Becquerel and her husband Pierre for their discovery of radioactivity. (In 1911 she received the Nobel Prize in Chemistry for the discovery of two new chemical elements, radium and polonium, the latter named for her homeland, Poland.) They and others observed that a radioactive substance could emit three types of radiation: alpha (), beta (), and gamma (). If the radiation from a radioactive source is passed between electrically charged plates, some particles are attached to the positive plate, some to the negative plate, and others feel no attraction. Which particles are positively charged, which are negatively charged, and which have no charge? Of the two charged particles, which has the most mass? Radioactivity. Alpha (), beta I(), and gamma () rays from a radioactive element are separated by passing them between electrically charged plates.arrow_forward
