What is the mass number of an atom with 5 protons and 7 neutrons? What element has 6 protons, 8 neutrons, and six electrons? What element has 4 protons 5 neutrons and 2 electrons? Which element has 16 neutrons, 15 protons, and 15 electrons? What isotope has 8...
atom呢? 答案 就是单数复数啦...比如说proton就是一个质子,protons就是多个质子……氢就是one proton……在这几个词中,nucleus比较特殊.nucleus是单数,nuclei是复数【参见半径单数=radius复数=radii】相关推荐 1英文词汇:molecules,nucleus,protons,neutrons,electrons一定要加S么,为什么.还是一般情况?atom呢?
Research and experimentation led them to the discovery of protons, neutrons, and electrons. Satisfied with their discovery, they could not have possibly imagined anything smaller than a proton or a neutron, which is about 10-15 in diameter. The first idea for a smaller particle came in 1935 ...
An atom has 75 protons, 74 electrons, and 112 neutrons. What is the charge of the atom? What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? What is a negatively charged atom called? According to the Rutherford-Bohr model, what is the structu...
1 An atom of an element has an atomic number of 6 and a mass number of 12.(a)Using this information, complete the table to show the numbers of protons,neutrons and electrons in one atom of this element.(2)number of protons number of neutrons number of electrons(b)The Periodic Table ...
Different number of protons All of the above Atom Structure And Isotopes: Quiz! Atom Structure and Isotopes: Quiz! Explore the fundamentals of atomic structure and isotopes with this engaging quiz! Test your knowledge on the relationship between protons, electrons, and neutrons, understand atomic cha...
Matter wave interferometry with electrons and neutrons has allowed many interesting demonstrations of quantum mechanical effects. A good example is the demonstration of the role of potentials in quantum mechanics: In 1959 Aharonov and Bohm showed that an infinite solenoid piercing an electron interferomete...
Each atom has a definite number of neutrons, protons, and electrons. The number of protons in the nucleus is called the atomic number, Z, and this number defines the chemical element that describes the atom. In a neutral atom, the number of electrons is equal to Z, and these orbit the...
Atoms with more than one shell are most stable when the outermost shell contains electrons. a. 10 b. 1 c. 8 d. 6 An atom of sodium has an atomic mass of 23 and an atomic number of 11. The atom contains how many protons, neutrons, and electrons?
So, you know you need 6 protons to make a model of carbon. To make a carbon atom, make 6 protons, 6 neutrons, and 6 electrons. Bundle the protons and neutrons together to make the nucleus and put the electrons outside the atom. Note that the model gets slightly more complicated when ...
