Do isotopes have the same atomic number? In order to find an accurate age of a living organism, we have to compare the amount of carbon to what other isotope? How do the nuclei of different isotopes of an element vary? If Atom #1 has 19 protons and 22 neutrons, and Atom #2 has 20...
金属铊的化合物具有很强的毒性。 铊金属被怀疑为人类致癌物。 方铅矿矿物中含有铅它的金属几乎87%,方铅矿是硫化矿物。 金属铅当今最好的来源是由回收的汽车电池。 2.2 来源 发现作为副产物, 金属矿藏, 矿物矿石 地球的地壳, 发现矿产, 矿业, 金属矿藏, 矿物矿石 ...
How did the results of this experiment lead Rutherford away from the plum pudding model of the atom to propose the nuclear model of the atom? If Rutherford had not known about Thomson's work on the atom, how might his model of the atom have been different? What did Ernest Rutherfor...

Atoms of the same kind have similar protons and electrons. Same type of atoms may differ due to the number of neutrons present, and these are known as isotopes. Atoms can join with other atoms in various ways, thus form thousands of molecules. All elements have a diatomic or polyatomic arr...
Nitrogen oxide (NO) has a double bond between the nitrogen atom and the oxygen atom (and there is an unpaired electron on nitrogen atom). Carbon monoxide (CO) has a triple bond between carbon and oxygen atoms. What are the Similarities Between Homonuclear and Heteronuclear Diatomic Molecules?
One neutron is added to the nucleus of an atom of Carbon-12. How has the atom been changed? Does it have a greater atomic mass? Compared to an electron, a positron has: a. the same mass and charge b. different mass and charge c. the same charge, but a diffe...
different isotopes of an element. b. a neutral atom and an ion of the same element. Explain how the fission can be slowed in the nuclear reactor. Is uranium-235 more likely to undergo nuclear fusion or nuclear fission? Explain. A nuclear scientist attempts to perform exp...

addition, if an isotope has 114 protons, it is a stable isotope. Moreover, if there are 126 or 184 neutrons present, they are also stable isotopes. In addition, if the ratios between protons and neutrons in an atom are even numbers, then these isotopes are most probably stable isotopes....
