Answer:
<em>6960000 Nickel atoms</em>
<em></em>
Explanation:
radius = 125 pm = 125 x 10^-12 m
diameter of each atom = 125 pm x 2 = 250 pm = 250 x 10^-12 m
span of distance to be achieved = 1.74 mm = 1.74 x 10^-3 m
number of nickel atoms = (1.74 x 10^-3 m)/(250 x 10^-12 m) = <em>6960000 Nickel atoms</em>
Answer:
Option 1.
Explanation:
When we warm up, our heart rate increases and we require much more energy to continue. Hence, our body absorbs much more oxygen from the surroundings, digest food and etc.
Sorry if the explanation might sound wrong, I learned this during science 2 years ago so I forgot.

Answer:
3. atoms, ions, or molecules
Explanation:
A crystal is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Hope this helps!
If it is in pure form, then only one type of atom. Negating if it has partially oxidized
