False
Trigonal planar because it has three bonding pairs and one lone pair
NH2- is sp3 hybridized and there is 2 bonding and 2 lone pair of electron,that's why shape of NH2 is angular.
Well, darling, the electron-pair geometry for As in AsO2- is trigonal pyramidal. Don't let the fancy terms scare you, it just means that the electron pairs around the As atom are arranged in a pyramid shape with one lone pair and three bonding pairs. So, As is strutting its stuff with a sassy pyramid vibe in this molecule.
This is Avery big question, but if you want to lay tiles: 1- What type, ist ceramic, granite synthetic or natural , marble . anyway. first look at the back of the tile , it has square pattern , if its low pattern then you need to add cement grout , choose self leveling of rough type that type that can provide more than one inch thick , chooz 2- component cement plus bonding agent , mix add to the back of the tile , let dry , then spray water for curing. Now you have more surface area to bond to the floor or walls . Seconed : alwayes use bonding agent when you use ready mix tile grouts (cement based plus SBR or Acrylics ) ( in Iraq we mix sand with cement at rate of 4 to 6 sand by volume with one part of cement and add latexes ). third : you better wash the floor , befor laying tiles. fourth: use slurry from the same cement based tile grout with the bonding aget but add more water to get primer . sixth: brush the floor with the primer, if the floor ios totaly dry , spray with water , or add little bit water to the slurry-primer( DO NOT LET IT DRY ) ( repeat the primer befoire laying the tiles). Seventh : Prepare the tile grout, add to the already rough surface of the tile , let one good highly skilled tile layer do the work , after laying the tiles, use mask tape to the sides of the tiles , add or fill the jionts with ready mixes , but always add bonding agent . You can use for foolrs, fountains , swimming pools also , i use aliittle bit more SBR latex and seal the floor with SBR 1 part plus 3 parts water plus one part cement , plus asmall handfull of very fine sand , brush kitchin floors, bathrooms, swimming pools, fountains, it last for ever . He tip is: latexes improves the mortar , it has strong bonding , and most important its flexibility , not mentioning water proofing , termite , insects that cannot housae itself in the mortar - latex formula .
Mixing grout and mortar together is not recommended, as they serve different purposes and have different properties. Mortar is designed for bonding masonry units like bricks and stones, while grout is used to fill gaps and provide support in tile installations. Combining them can compromise the strength and flexibility needed for each application, leading to potential issues down the line. It's best to use them as intended for optimal results.
Ionic and covalent bonding involve electrons. Ionic bonding involves the loss and gain of electrons, form ions. Covalent bonding involves the sharing of electrons.
Covalent bonding involves the sharing of electrons. Ionic bonding involves the transfer of electrons.
covalent bonding is used to share electrons
SiF4 has covalent bonding. Each silicon atom shares one of its four valence electrons with each of the four fluorine atoms, forming four covalent bonds.
covalent bonds
Covalent bonding is formed when atoms share electrons. In this type of bonding, atoms share one or more pairs of electrons to achieve a more stable electron configuration.
false, it would be true if it didn't say ionic and instead said covalent bond.
This is a covalent bond.
In covalent bonding, atoms share electrons to achieve a full outer shell. This contrasts with ionic bonding, where electrons are transferred. One phrase specific to covalent bonding is "electron sharing."
Nitrogen has 5 electrons available for covalent bonding. It has 5 electrons in its outer shell, meaning it can form stable covalent bonds by sharing these electrons with other atoms.
electrons are shared between one or more atoms
No, in covalent bonding atoms "share" electrons. In ionic bonding one atom completely takes on or more electrons away from another.
