How many bonds can nitrogen have? Which rule or principle should be used? A) Five bonds; octet rule. B) Three bonds; octet rule. C) Three bonds; the Hund's rule. D) Five bonds; the Aufbau Principle. correct answer: B When two hydrogen atoms meet, they will attract to each other and form a bond (and a H2 molecule). Why? A) Because electrons like to stay together. B) Because electrons like to be paired up. C) Because there is attraction between the electron in one hydrogen atom an...

AQA 2023 AS CHEMISTRY QUESTIONS WITH 100% CORRECT ANSWERS Absolute temperature - ANSWERS Temperature measured in Kelvin Absolute zero - ANSWERS The lowest possible temperature theoretically achieveable - 273.15 degrees celius or zero Kelvin Acceleration - ANSWERS The stage in mass spectrometry where positive ions are speeded up by an electric field Acid rain - ANSWERS Rain that has been acidified by pollutants such as sulfur dioxide Actual yield - ANSWERS Mass of product obtained in a ...

Rutherford's Gold Foil Experiment - proposed that atoms consist of a tiny, massive, positive nucleus surrounded by electrons nucleus - contains all the positive charge and nearly all the mass of the atom James Chadwick - discovered the neutron cathode rays - move from negative electrode to positive electrode (like electrons in a voltaic cell) Thompson's Cathode Ray Experiment - discovery of the electron (also the discovery that atoms are divisible into smaller particles) Milliki...

How many electrons can each orbital hold? Two How many electrons can be held in each sub shell? S - 2 P - 6 D - 10 F - 18 Put the sub shells in order do their energy, lowest to highest S, p, d and f How do we fill the p and d subshells singly first and then doubly What is an orbital? A region of space around the nucleus where there is a 95% chances of finding an electron What is the Aufbau principle? An electron occupies the lowest-energy orbital that can receive it What ha...

Decomposition reaction - ANSWERStarts with one reactant and ends with two or more products. Synthesis/formation/combination reaction - ANSWERStarts with two reactants and ends up with one product. Single displacement - ANSWERUncombined element takes place of the combined element in the compound. Double displacement - ANSWERBoth reactants are compounds and both products are compounds. Combustion reaction - ANSWERWhen reactants are oxygen and a hydro-carbon and the products are water a...
