Explanation:
The power of a bond, single, double and triple.
Answer:
6.02 × 10²³ atoms.
Explanation:
According to the Avogadro number, the one mole of any substance have 6.02 × 10²³ atoms.
The number 6.02 × 10²³ is called Avogadro number. it is the number of atoms, ions or molecules in one gram atoms of element, one gram ions of substance or one gram molecules of a compound.
For one mole of magnesium.
24.305 g of Mg = 1 mole of magnesium = 6.02 × 10²³ atoms of magnesium.
Other example includes:
18 g of water = one mole of water = 6.02 × 10²³ molecules of water.
23 g of sodium = one mole of sodium = 6.02 × 10²³ atoms of sodium.
False, I think.
I would say it is determined by the number of electrons. The number of protons determines what element it is.
An element will try and fill it's outer shell, and so elements such as neon (a noble gas) is difficult to do anything with as it already has a full outer shell of 8 electrons. Something with 7 outer electrons, however, will be much more reactive as they will try to fill up that last space through a chemical bond.
Not sure if I explained that very well haha,
basically i would say false
