解析 首先句子后面是作定语的,由主句可以知道,修饰的是主语element.因为atoms是原子的意思,对于元素来说,逻辑关系自然是“元素里的原子”,所以element和atoms具有从属关系,用whose(注意啦!在定语从句表示从属关系的时候,关系词whose不仅仅适用于人,也可以适用于物)...
How do I interpret the element boxes? Located right above the Englishname for each element, the largest letters represent itschemical abbreviation. The largest number is the element’satomic number. Other information in the box includes the element’s electron configuration, electronegativity, oxidation...
Although the image of atomic coordinates in the first demonstration shows no Z-contrast (where Z is the atomic number of the element), the OCSVM can work for STEM images exhibiting Z-contrast if the dopants are excluded since dopants can complicate the one-class classification. ...
For any element, the mass number is equal to the atomic weight rounded off to the nearest integer value. The proton has a positive charge that is equal in magnitude, but opposite in polarity, to the charge of an electron. The number of protons defines how many extranuclear electrons an ...
CAS Registry Number:7439-95-4 Magnesium Trivia: Magnesium was originally named 'magnium' by Humphrey Davy after isolating the element from magnesia, known now as magnesium oxide. The 1915Nobel Prize in Chemistrywas awarded to Richard Willstätter for his work with the chlorophyll and identifying ...
At the present time, the best studied has been the isotope of element 103 with mass number 256, synthesized in Dubna. In 1965 a value of the half-life of 45±10 sec was obtained for it by observation of the daughter products of decay. In the 1967 studies it was established for this ...
