In a chemical formula, a unit containing three atoms can represent various compounds. For example, water (H₂O) consists of three atoms: two hydrogen atoms and one oxygen atom. Another example is ammonia (NH₃), which has three hydrogen atoms bonded to one nitrogen atom. These simple molecular structures illustrate how three atoms can combine to form distinct chemical entities.

What are 3 atoms in each formula unit?
In a formula unit, the three atoms can vary depending on the substance being described. For example, in sodium chloride (NaCl), there are one sodium atom (Na) and one chlorine atom (Cl). In calcium carbonate (CaCO₃), the formula unit consists of one calcium atom (Ca), one carbon atom (C), and three oxygen atoms (O). Another example is water (H₂O), which contains two hydrogen atoms (H) and one oxygen atom (O).
Each proton and neutron has an atomic mass unit amu?
Yes, that is correct. A proton and neutron each have a mass of approximately 1 atomic mass unit (amu). This unit is commonly used to express the mass of subatomic particles in relation to the standard carbon-12 atom.
How many atoms are there in silver per unit cell?
In a face-centered cubic (FCC) structure, which is the crystal structure of silver, there are four atoms per unit cell. This is calculated by considering the contributions from the corner atoms (1/8 of an atom each from 8 corners) and the face-centered atoms (1/2 of an atom each from 6 faces). Therefore, the total is 1 (from corners) + 3 (from faces) = 4 atoms per unit cell.
What does the name helium-3 tell about this atom?
The name helium tells that its atomic number is 2, containing 2 protons in each atom. The numerical part of the name shows that each atom also has one neutron.
How many protonsnutrons and electrons are in lithuim?
Lithium's atomic number is 3. Thus, it has 3 protons in each atom, all of which have a +1 charge. To be electrically neutral then, lithium must also have 3 electrons per atom.
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.
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 has 3 atoms in each formula unit?
Water (H2O) has 3 atoms in each formula unit.
Is lithium an atom?
Lithium is an element with 3 protons in each atom.

What is the oxidation number of AlF6-3 central atom?
The oxidation number of the central atom Al in AlF6^3- is +3. This is because each F atom contributes a -1 charge, and the overall charge of the complex ion is -3, so the Al atom must have a +3 oxidation state to balance it out.

How many atoms present in 3MgO?
There are a total of 6 atoms present in 3MgO. This is because each formula unit of MgO consists of one magnesium atom and one oxygen atom, so for 3MgO, you would have 3 magnesium atoms and 3 oxygen atoms, totaling 6 atoms overall.
What is the oxidation of each individual carbon atom in C2O4?
+3
