peripheral atoms an (3) preferred number of bonds formed by each peripheral atom. Overall there will be a distribution of bonding and possibly non-bonding valence electrons around the central atom. This determines the shape of the molecule, with each sh...
periods. The period number of an element signifies the highest energy level an electron in that element occupies (in the unexcited state). The number of elements in a period increases as one traverses down the periodic table because as the energy level of the atom increases, the number of ...
The orbital principle is still the same as a comet orbits an imaginary line that links our sun to some distant orbital companion. This recalls the classical description of an elliptic orbit, where we are told there are two “focal points” of an ellipse that determine the orbit. One of tho...
There are four different seasons on Earth: spring, summer, autumn, and winter. However, some parts of Earth do not have all four seasons and are permanently cold or hot. Answer and Explanation: Earth's revolution around the sun causes the different seasons. Since the Earth is tilted on its...
The moon phases are determined by the amount of illumination the sun shines on the moon. This illumination determines the overall visible shape of the moon. The moon goes through eight different phases that determine its visible shape. Answer and Explanation:1 ...
This determines the perspective geometry of the image. The shorter the focal length, the more perspective distortion is introduced and the wider the FoV. Lens Distortion Lenses only approximate perspective geometry. As a result, they distort the placement and shape of objects imaged on the focal ...
the height the transition to warming from cooling starts wherever 0.1 Bar occurs. So the lapse rate to space is mainly a function of gas pressure which determines the lapse rate (gradient) any such process will naturally have. Our surface temperature is not mysterious. It’s warmer because our...
Though atomic structure and crystal structure are related, they are representationally different. The structure of each is typically represented with drawings and identifying factors. Answer and Explanation: The structure of a substance is a key identification factor. You can distinguish salt from s...
In this case, the magnetic fields created by those spins point in opposite directions, so they cancel each other. However, some atoms contain one or more unpaired electrons, and these unpaired electrons create a tiny magnetic field. The direction of their spin determines the direction of the ...
Both the protons and neutrons reside in the nucleus. Protons have a postive (+) charge, neutrons have no charge --they are neutral. Electrons reside in orbitals around the nucleus. They have a negative charge (-). It is the number of protons that determines the atomic number, e.g., H...
