Three electrons in their valency orbit.
a molecule with 3 atoms and 2 elements
There are two elements in period 3 that are expected to be paramagnetic in the gas phase: sodium (Na) and sulfur (S). These elements have unpaired electrons in their outermost electron shells, making them paramagnetic.
All of these elements belong to same period. The period number is 3.
period 3
3 different elements, silver carbon and oxygen. 6 atoms total.
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
there are 5 atoms (1Na 1Cl and 3O) and they are all elements.
The period number is equal to the number of energy levels. Elements of period 3 have 3 energy levels. Na,Mg,Al,Si are few elements in the period 3.
Be spoonfed then: 3 carbon atoms, 6 hydrogen atoms and 3 oxygen atoms.
There are 2 elements that all the organic compounds have. They are carbon and hydrogen. Most organic compounds contain oxygen.
DDT contains 3 elements: carbon, hydrogen, and chlorine.
Three different elements: C, H, O. 3 C-atoms 8 H-atoms 10 (=3*2+4) O-atoms
