Under ambient conditions, it crystallizes in a cubic unit cell and is very stable with one sodium atom (Na) and one chlorine atom (Cl). According to the octet rule, all chemical>
A gravity model of the Earth constructed with data from GRACE. Credit: University of Texas Center for Space Research and NASAIt is all about gravity these days. First came GRACE (Gravity Recovery and Climate Experiment) and then we'll have GOCE (Gravity field and steady-state Ocean Circulation Explorer). I'll reveal>
The landing of a cute robot on Mars really resonated with American popular culture this past weekend; and so the first few images Curiosity snapped have caught fire as well, including a blotch that was no longer there in later pictures.Curiosity landed at 10:32 p.m. Aug. 5 PDT near the foot of a mountain three miles>
