An isotope has 15 protons, 16 neutrons, and 15 electrons. What is the isotopic notation of the isotope
1 answer:
Answer:
is the isotopic notation of the atom
Explanation:
The isotope notation is:
<em>Where a is the mass number = Number of protons + Number of neutrons</em>
<em>b is atomic number = Number of protons</em>
The atomic number define the nature of the atom, the element with atomic number = 15 is phosphorus, P:
a = 15 protons + 16 neutrons = 31
b = 15
is the isotopic notation of the atom.

Explanation:
In liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.
In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.
So, when at 298 K and 1 atm exists in liquid state and
exists as a gas then it means there occurs strong force of attraction between the molecules of
due to which it exists in liquid form.
Thus, we can conclude that at 298 K and 1 atm, bromine is a liquid with a high vapor pressure, whereas chlorine is a gas. This provides evidence that, under these conditions, the forces among molecules are greater than those among
molecules.
Notes:-
- S has Z=16
Electronic configuration
- 1s²2s²2p⁶3s²3p⁴
So
- Valency is 4 and 6
- Three fluorine atoms take 3 electrons and one lone pair present over S
- As one electron remains unshared so we use + sign .
