Answer:
The area around the nucleus must be of low mass.
Explanation:
Rutherford`s experiment showed that there are some positive charges in the center of the atoms, and because they are all together, they will give a great mass to the atom.
It was quite different from Thomson`s experiment, in which it was thought that the negative charges were mixed with the positive charges, around the atom (like a Pudding Model). In Rutherford`s experiment, because the direction of beta particles, it was the prediction of the positive nucleus.
Hope this info is useful.
Answer:
Metallic compound
Explanation:
Metallic compound -
A metallic compound refers to the species having at least one metal, is known as a metallic compound.
In general a metallic compound consists of two ions, a positive ion or the cation, is is basically a metal, and,
a negative ion or an anion, which is a non - metal.
Hence, from the given statement of the question,
The correct answer is - metallic compound.
1 mole of any substance contains Avogadro's number.
So, 1 mole of O2= 6.023x10^23 molecules
3 mole of O2= 6.023x10^23x3 molecules
= 1.8069x10^24 molecules
Each molecule of Oxygen has 2 atoms.
therefore,
1.8069x10^24 molecules= 1.8069x10^24 x 2 atoms
= 3.6138x10^24 atoms.
Answer:
Explanation:
Hello,
In this case, since the density is defined as the ratio of the mass and volume:
We can compute the mass of blood as follows:
