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,
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?
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 ...
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 ...
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 ...
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?
- Protons have a positive charge (+1). - Neutrons have no charge (neutral). - Electrons have a negative charge (-1). 3. Location of Subatomic Particles: - Protons and neutrons are located in the nucleus (the center of the atom). - Electrons are found outside the nucleus and move in...
Physics. the smallest component of an element having the chemical properties of the element, consisting of a nucleus containing combinations of neutrons and protons and one or more electrons bound to the nucleus by electrical attraction; the number of protons determines the identity of the element....
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...
Calculate the atomic mass of an atom with 6 protons, 6 electrons, and 7 neutrons. Identify the element, its atomic number, mass number, and electrical charge of the following: | No. of Protons | No. Neutrons | No. of Electrons | Elem...
