<u>¹⁴₇N</u><u> </u>is the more stable isotope
<h3>
Briefly explained</h3>
We have ¹⁴₇N which has a neutron to proton ratio of one, and we look at ¹⁸₇N which has a neutron to proton ratio of 1.57 Again, you look at table 24 to and you see the atomic number of seven and there is really no stable isotope. It has any more than 10 neutrons.
When we have eight, protons will go down seven protons. There's really nothing stable that has more than maybe eight neutrons. So the fact that we have 11 neutrons with ¹⁸₇N suggests that this is very unstable and
¹⁴₇N is the stable isotope of the pair.
<h3>
Stable and Unstable Nuclei</h3>
An atom is electrically neutral. It contains an equal number of positively charged protons and negatively charged electrons and their charges balance. The nucleus however contains only positively charged protons which are closely packed together in a very small volume (remember neutrons have no charge).
From the laws of physics (Coulomb’s Law) one would expect that the protons being of the same charge and so close together would exert strong repulsive forces on each other. The combined gravitational force from the protons and neutrons in a nucleus is insignificant as an attractive force because their masses are so tiny.
This implies there must be an additional attractive force similar in size to the electrostatic repulsion which holds the nucleus together.

Answer:
The answer to your question is 200 g
Explanation:
Data
mass of water = ?
mass of NaOH = 4 g
concentration = 2 %
Formula
% mass = mass of solute/mass of solution x 100
-Solve for mass of solution
mass of solution = mass of solute / % mass x 100
-Substitution
mass of solution = 4 / 2 x 100
-Simplification
mass of solution = 2 x 100
-Result
mass of solution = 200 g
Answer:
The appropriate option will be Option A (unequal sharing of electrons in a covalent bond).
Explanation:
- A polar bond seems to be a covalent bond amongst two or even more atoms where there is an uneven distribution of the electrons surrounding the connection.
- This induces a small electrical magnetic dipole in the molecules whereby the end becomes generally favorable and another is mildly controversial.
The other choices aren't relevant to the situation presented. The answer above would be appropriate.
