What is formular for density?
Mass per unit volume (kgm-3)
How many electrons shared in aluminum oxide?
Al2O3, each formula unit would have 6 shared electrons. Al wants 3 electrons per atom and O can give 2 electrons per atom.
How many electrons will there be in each atom of lithium?
3 total
How many atoms in LI OH?
I'm pretty sure there are 3 atoms because in Li2o, there are 2 atoms in lithium and 1 atom in oxygen.
Each proton and neutron has an atomic mass unit amu?
Each proton and neutron has an atomic mass unit (amu) of: 1 3 4 2

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.
How many carbon atoms are in the diamond unit cell?
In a diamond unit cell, each carbon atom is located at the corners of the unit cell. Since there are eight corners in a unit cell, each shared by 8 adjacent unit cells, the contribution to the total number of carbon atoms is 1/8 of a carbon atom per unit cell. Therefore, there is 1 carbon atom per unit cell.
Is lithium an atom?
Lithium is an element with 3 protons in each atom.
How many electrons shared in aluminum oxide?
Al2O3, each formula unit would have 6 shared electrons. Al wants 3 electrons per atom and O can give 2 electrons per atom.
What is the formula for 3 equals alae-5.6 percent -px?
8.6
What is the oxidation of each individual carbon atom in C2O4?
+3
How many electrons will there be in each atom of lithium?
3 total
Number of atoms in hcp unit cell?
"There are 6 atoms in the hcp unit cell. The hex shape has six atoms at the points that are direct translations of each other making 1 atom for the top hex and one atom for the bottom hex. That's 2. The atom in the center of the top and center of the bottom are translations giving 1 more. That's 3. Then there are 3 atoms in the middle region of each cell bringing the total to 6." The answer should depend on how you choose your unit cell. In the primitive hexagonal cell we have 1 atom at each of the corners of the cell (each is "worth" 1/8) and 1 atom within the cell giving us 2 atoms/unit cell. (Note: the 'primitive hexagonal cell' above actually refers to the parallelpiped structure that the hexagonal unit cell consists of: the hexagonal 'unit' -it cannot technically be referred to as a unit cell, because unit cells are the most reduced form of the crystal structure- can be divided into 3 parallelepipeds.)
How many neutrons are there in 3 BeF2 molecules?
There are 10 neutrons for each F atom, and 5 for each Be atom, so each BeF2 molecule will have 10+10+5=15 neutrons. You need 3 molecules, so 3*15=45
What is the number of each type of atom in NaHCO3?
Sodium bicarbonate has: 1 sodium atom, 1 hydrogen atom, 1 carbon atom, 3 oxygen atoms.
How many valence electrons are in each atom?
well it can have 3 or more
