What kind of crystal lattice structure is formed when lithium and fluorine combine to form lithium fluoride?
Answers
The lattice structure of Lithium Fluoride (LiF) is comprised of positively charged lithium ions (Li+) and negatively charged fluoride ions (F-) that a linked together by ionic bonds.
The crystal structure of LiF corresponds to that of a face centered cubic (FCC) lattice with Li+ and F- ions occupying the lattice points in the unit cell.
Answer:
Explanation:
An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.
Lithium fluoride is a chemical compound formed through a chemical bond of formula LiF. The electronic configuration of Li is 1s12s1 and that of fluorine is 1s12s22p5. When these atoms come into contact, the 2s1 valence electron of the lithium is transferred to the F atom.
Ionic solids can crystallize in various types of networks, depending on the size of the ions that form it and the charge they possess.
The solid NaCl has a crystalline structure, in which each Na + ion is surrounded by six chloride ions in an octahedral geometry. Therefore, it has a coordination (6: 6) whose numbers indicate how many neighbors surround each ion. The number on the right indicates the neighbors of Na +, while the one on the left, those of Cl–. The structure is based on a compact cubic packing (centered on the faces) of the anions and in which the cations occupy all the octahedral holes. The structure can also be seen as a compact cation packing structure with the anions occupying the octahedral holes. In each unit cell ions of one type occupy the vertices and centers of the faces of the cube while those of the opposite sign are located in the centers of the edges and in the center of the cube.

The greenhouse effect is the process whereby there is radiation from a atmosphere planet and the planet increase the temperature of the planet's surface to a temperature above normal.In this process the Earth's atmosphere becomes thicker with the influence substances such as gases
and the radiation coming from the sun is trapped, then the Earth becomes warmer. Green house effect is seen in global warming.
Carbon neutral can be described as a process of removing huge amount of carbon dioxide from the atmosphere in order to achieve zero carbon neutrality.It is also reffered to as carbon neutrality, and this can be achieved by actions of organizations, businesses and individuals .
Carbon neutral can be achieved in two ways;
: 1.) Maintaining a balance between carbon dioxide emissions and carbon removal by means of the process called carbon offsetting
2 ) the process of removal of carbon dioxide from the atmosphere in order to balance up emissions in another place.
Carbon positive is crucial to increase the positive influence of our daily activities on climate change and our resources.
while reduce the negative effect of our activities and business on evironment.
Therefore, the practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to greenhouse gas emissions by purchasing credits from "carbon-positive" projects to balance out emissions is true because the harmful gasses that is been released to the atmosphere is balance up by the carbon neutral process hence the reduction in green house effect.

formula represents a hydrocarbon. Therefore, option (2) is correct.
Hydrocarbons are merely carbon and hydrogen. Aliphatic or aromatic. Aliphatic hydrocarbons are saturated or unsaturated open-chain hydrocarbons.Saturated aliphatic hydrocarbons have single bonds, while unsaturated ones have double or triple bonds.
Aromatic hydrocarbons have alternating double bonds in a ring.Only option 2——is a hydrocarbon. Butane, a saturated aliphatic hydrocarbon, with four carbon and 10 hydrogen atoms.
