what number of the orbitals are thoroughly stuffed? what percentage of the orbitals are linked to the atom’s n = four crucial power point? 3s, 3p, and 3d orbitals. Why does its electron-dot constitution convey merely dots? a hundred and one. X Ray An X-ray photon has an power of 3.01 × 10 -18 J. what's its frequency and wavelength? 102. Which point has the ground-state electron configura- tion represented through the noble-gas notation [Rn]7s 1? X ■ 103. How did Bohr clarify atomic emission spectra? determine 5.26.
Repetition of chemical and actual houses of the weather once they are prepared via expanding atomic quantity is named the periodic legislations. VOCABULARY interpreting fee examine and distinction the ways that Mendeleev and Moseley prepared the weather. be aware beginning Periodic comes from the Greek notice periodos, that means means round, circuit desk 6.2 summarizes the contributions of Newlands, Meyer, Mendeleev, and Moseley to the improvement of the periodic desk. The periodic desk introduced order.
Interactive determine to work out an animation of ozone depletion, stopover at glencoe.com. and ozone in Molina and Rowland’s speculation happen excessive overhead. Many variables are concerned. for instance, there are numerous gases found in the stratosphere. therefore, it might be tough to figure out which gases, or if all gases, are inflicting reducing ozone degrees. Winds, adaptations in ultraviolet mild, and different elements may perhaps swap the result of any test on any given day, making comparisons tricky.
quantity to 4 major figures, and write the reply in medical notation. a. 0.00054818 g c. 308,659,000 mm b. 136,758 kg d. 2.0145 mL Addition and subtraction if you upload or subtract measurements, the reply should have an analogous variety of digits to the appropriate of the decimal because the unique price having the fewest variety of digits to the fitting of the decimal. for instance, the measurements 1.24 mL, 12.4 mL, and 124 mL have , one, and nil digits to the fitting of the decimal, respectively.
