an element is a substance ,all of ___ atoms have the same atomic number为什么选whose ?. 答案 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...
To determine the block, group number, period, and outer shell electronic configuration of the element with atomic number 107, we can follow these steps:Step 1: Identify the nearest noble gas The atomic number of the element is

interacting BECs, (b) interacting BECs of [Math Processing Error]5×104 atoms with s-wave scattering lengths [Math Processing Error]as=±0.1a0 ([Math Processing Error]a0 is the Bohr radius), and (c) interacting BECs of [Math Processing Error]103 atoms with [Math Processing Error]as=±1.0...
environments, and, thus, employed a ‘full’ separation of atom types with further details provided in Supplementary Note2. In selected cases, to better assess the trade-off between performance and efficiency, we also performed parametrization runs choosing only a single atom type per element. ...
A mixture contains a matrix material containing specified units; and a material which is capable of emission and which contains an element of atomic number above 20. A mixture contains (a) a matrix material containing units of formula C:Q where Q = a non-bonding electron pair comprising O,...
of energy from the incident photon to the detector material can mainly occur in three different ways: Compton scattering, photoelectric absorption, and pair production [48], each of which is predominant in a certain energy range, which also depends on the atomic number of the element involved. ...
In addition, crystal degradation correlating with the difference in thermal expansion is eliminated by keeping the total III-V layer thickness thinner than ~350 nm. As a result, various III-V photonic-device-fabrication technologies, such as buried regrowth, butt-joint regrowth, and selective area...
