Flashcards do conjunto (17)
- 1What does the arrangement of electrons determine?Properties and behavior of elements
- 2When light passes through a prism, it produces a ...Atomic emission spectrum
- 3What does white light produces? How come?A continuous spectrum
Due to many chemicals continuously burning - 4What does AES consist of?Separate lines of colours
- 5What is Schrodinger's principle?Electrons act like waves
- 6What is the Quantum model?A refined version of the Bohr's model, which uses mathematical equations to describe the likelihood of finding an electron in a certain position
- 7Limitations of Bohr's modelCould not mathematically predict lines in emission spectrum, of complex atoms.
Did not explain why electrons move around the nucleus and the differences of energy between electrons - 8What is the probability of finding a electron?90%
- 9What are orbitals?Areas within atoms where there is a high probability of finding an electron
- 10Which elements have an irregular electron configuration?Chromium and Copper
- 11What is the stability of subshells?Filled > Half-filled > Partially
- 12What is an elementsubstances that are made up of only 1 type of atom
- 13What determines a type of atom?number of protons
- 14What is an isotope?atoms that have same number of protons but dif neutrons
- 15When adding or removing a neutron, the atoms becomes?unstable
- 16What does it mean to be unstable?It can't be found in nature, it may be man-made
- 17Define Atomic Massweighted average mass of an element, based on the relative natural abundance of that element's isotopes
