Answer:
The number of Aluminium atoms present in per cubic meter is 
Explanation:
Given the density of Aluminium 
is 
And the atomic weight of Aluminium 
is 
Also, the Avogadro's number 
is 
We need to find the number of atoms per cubic meter 
Plug the given values in the formula we get,
So, the number of Aluminium atoms present in per cubic meter is 
Answer:
Electrons get farther from the nucleus.
Explanation:
By going from the top to the bottom of a group, the atomic number increases. That would mean that:
- The number of orbitals increases, as there are more electrons.
- A higher atomic number implies an increasing number of neutrons.
- As there are more electrons, they get farther from the nucleus. The farther an electron is from the nucleus, the easier it is for the electron to be removed from the atom.
0 degree Celsius is equal to 272 k
So to convert C to k we need to add 273
To convert K to C we need to subtract 273
Answer:
Because you can physically see the object melting when it comes to the melting point. The objects texture, color, temperature, shape, and state of matter (solid, liquid, gas) are possibly changing.
