A central atom attached to 3 other atoms, all lying on the same plane.
A pyramid is a generic term and can have any number (>3) of plane faces. A triangular pyramid has 4 faces, a rectangular one has 5, and so on. A pyramid whose base has n sides has n+1 faces.
Yes
Yes, the world "linear" and "line" have the same root.
No. Pyramids are three-dimensional, and hence cannot be drawn within a single plane.
BH3 has a trigonal planar shape with 120 angles.
So the cutter can get the exact shape the cutter wants if the plane fits into the plan for the cut. The tetrahedral plane is the diamond's weakest plane.
The amide ion has a trigonal planar shape, with a nitrogen atom at the center surrounded by three atoms in the same plane.
Out of the given molecules, methane (CH4) and ethane (C2H6) will lie flat on a plane. Methane has a tetrahedral shape with carbon at the center and four hydrogen atoms attached to it, while ethane has a linear shape with two carbon atoms bonded together and six hydrogen atoms attached to the carbons. Ethene (C2H4), ethyne (C2H2), and chloromethane (CH3Cl) have bent or trigonal planar geometries, which means they won't lie flat on a plane.
Four atoms bound to a central atom with no lone pairs.
The name "trigonal bipyramid" comes from the geometry of the molecule, as it consists of a central atom surrounded by five other atoms or groups of atoms arranged in a trigonal plane. Additionally, it has two other atoms or groups of atoms situated above and below this plane, creating a shape resembling two pyramids joined at their bases.
The bond angle in C2H2 (acetylene) is 180 degrees. This is because acetylene has a linear molecular geometry due to the presence of two carbon atoms with a triple bond between them, resulting in a straight line structure.
A central atom attached to 3 other atoms, all lying on the same plane.
The shape of a PCl5 molecule is trigonal bipyramidal, with three equatorial bonds and two axial bonds. The lone pair on the central phosphorus atom occupies one of the equatorial positions, resulting in a seesaw shape.
A pyramid is a generic term and can have any number (>3) of plane faces. A triangular pyramid has 4 faces, a rectangular one has 5, and so on. A pyramid whose base has n sides has n+1 faces.
Trigonal pyramidal - don't forget nitrogen's lone pair.
