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.
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.
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.
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.
The dot structure begins with a P atom in the center, with four singly bonded O atoms, one at each cardinal direction. Each O atom has a pair of dots on the unbonded sides. Finally, the structure is bracketed and noted with a 3- superscript.
Millimeters are a unit of length, and liters are a unit of volume, so they do not convert into each other.
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.
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.
Water (H2O) has 3 atoms in each formula unit.
Lithium is an element with 3 protons in each 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.
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.
+3
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.
Aluminium trichloride has 4 atoms in the formula unit.

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
