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) ...

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
atomic planes relative to the Mn atoms measured along the crystallographicc-axis (Δz || c). The Mn planes serve as a reference system so that Δz(Mn-Mn) = 0. We observe maxima in the counts for Δz(Er-Mn) at about ±0.25 nm with a periodicity of 0.51 nm, ...
Absorption spectroscopyis widely used for the study of atmospheric-pressure plasmas. Species with a large absorption cross-section in the UV are studied most frequently due to the experimental simplicity. One challenge, however, is the large number of competing processes with significant absorption in...
(See Supplementary Note 8) Here each t’ should be interpreted as an off-diagonal matrix element for an effective two-level Hamiltonian near the avoided crossing and distinguished from the nearest neighbor hopping amplitude t in the Fermi-Hubbard Hamiltonian. However, we find that the magnitude ...
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,...
The creation of a complex of the ATP-bound DnaA protein oligomer and duplex oriC DNA is critical for local unwinding of an AT-rich DNA unwinding element (DUE)2 in oriC and for binding of DnaA protomers to single-stranded DUE (3). Comparative structural studies of the initiator proteins ...
which is very close to the Fermi level (EF), comprises Cl-3sorbital and Sn-5s/5porbitals, while the nearest conduction band (very close to theEF) is composed of Sn-5pand Cl-3sorbitals. The prime contribution to the conductivity could come from the Sn element, as seen in Fig.2b. The...
We find that 31 out of the 55 materials that do not have smooth interpolations contain atoms with nonzero magnetic moments, mostly containing 3delements (V, Cr, Mn, Fe, Co, Ni) and one containing the5delement W. We found 26 materials to have several discontinuities in total energy (even...
