两个逗号之间的however有什么作用?例句:Atomic number is,however,defined in terms of protons,because electrons are lost or gained when ions ions are formed in chemical reactions.
Any two atoms that have the same number of protons belong to the same chemical element. But atoms with an equal number of protons can have a different number of neutrons, which are defined as being different isotopes of the same element. These isotopes are often unstable, and all those with...
If the protons and neutrons are not equal, does that mean it is a radioactive isotope? How is nuclear chemistry different than particle physics? If atoms contain charged particles, why do they not have a charge? a. They have the same number of protons and electrons. b. Charge is loc...
Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative charges on all the electrons. But sometimes an atom can gain or lose an electron to become what's called an ion. If it ...
An element has an atomic number of 114 and an atomic mass of 285. How many protons, neutrons, and electrons does a neutral atom of this element have? An atom has an atomic number of 8 and a mass number of 17. How many protons, neutrons, and ...

英语懂的 来拿分 11.How many neutrons and pro tons are in an atom of phosphorus11.How many neutrons and pro tons are in an atom of phosphorus-31,atomic number 15,and determine how many electrons should be in the first,second,third,and fourth en
the same chemical element. But atoms with an equal number of protons can have a different number of neutrons, which are defined as being different isotopes of the same element. These isotopes are often unstable, and all those with an atomic number greater than 82 are known to be radioactive...
Use the Periodic Table and mass number to evaluate atomic structure. The atomic number equals protons. The mass number minus the atomic number equals neutrons. In neutral atoms, electrons equal protons. In unbalanced atoms, find electrons by adding the o
