When a carbon forms four covalent bonds the bonds are directed toward the corners of what geometric structure?
tetrahedron
In a solid AB having NaCl structure. A atoms occupy the corners of cubic unit cell if all the face centered atoms along one of the axes are removed then the resultent staichiometry of thesolid is?
effective no. of A atoms = (8*1/8)+(4*1/2)=3 effective no. of B atoms = (12*1/4)+1=4 therefore formula of the solid = A3B4
What is the molecular structure of sulfate ion?
Thr polyatomic anion sulfate has a central S atom surrounded by O atoms at the corners of a terrahedron. The bond lengths are all the same, the bond angles are 109.5 o
Why should be filling be done from the corners to the center of the nails?
nails
What is the number of atoms in FCC unit cell?
A FCC or Face Centered cubic unit cell has 4 atoms. It is calculated like this. There are 8 corners of the unit cell and each corner has one atom.But each atom is shared by 8 unit cells. So. total no. of atoms at corners= 1/8 *8=1 atom . Also, there are 6 faces which have one electron in the centre of it. Each such electron is shared between 2 unit cells. This gives the total no. of atoms at the centre of faces of unit cell=1/2 * 6 = 3 atoms. Adding the two, we get four atoms in an unit cell 1+3=4 atoms.
What is the difference between face centered cubic crystal structure and hexagonal close pack crystal structure?
face centre cubic crystal has eight atoms in each corner and one atom in the centre of cubic unit cell.while hexagonal close packed structuree has only six atoms in corners but no in the centre of cubic cell
What is Body Centered Cubic?
Body centered is another cubic unit cell.This unit cell has atoms at the eight corners of a cube and one atom in the center. Once again, the corner atoms are bisected by three orthogonal the planes leaving one-eighth of each atom inside. The central atom is also inside, so this unit cell contains two atoms. Nickel is an example of a substance that has a body centered cubic crystal structure.
A solid with flat sides that meet at sharp edges and corners is called?
a solid with flat sides meet at sharp edges and corners is called crystal structure
A face-centered cubic cell contains 8 X atoms at the corners and 6 Y atoms on the faces What is the empirical formula of the solid?
XY3
When a carbon forms four covalent bonds the bonds are directed toward the corners of what geometric structure?
tetrahedron
what are the advantages of the round keep castle?
They didn't have any corners so an attacking army couldn't collapse the corners. The arch is a very strong structure, so it was harder to destroy with siege machines.
Were did the anasazi live?
The Anasazi Indians live on the Four Corners which is Colorado, New Mexico, Arizona, and Utah.
Brief introduction of icosahedral structure of virus?
20 sided ( or facets) vertex (12 evenly spaced corners)
What is a face centered cubic crystal?
A face-centered cubic unit cell is a cube. All sides are the same length and all face perpendicular to each other, with an atom at each corner and an atom in the middle of each face of the cell.
How many faces a cube have?
A cube has 6 faces. It also has 12 edges and 8 corners. Cubes are a three dimensional structure.

Can you square a circle?
No. A circle has no corners and a square has four corners. There is no object that has no corners and four corners.
