<u>Answer:</u> Both the given species are isotopes of the same element.
<u>Explanation:</u>
An isotope is defined as the chemical species that have the same atomic number but a different mass number.
The atom consists of 3 subatomic particles:
- Protons: They are positively charged particles present in the nucleus of an atom.
- Electrons: They are negatively charged particles present in the orbits around the nucleus of an atom.
- Neutrons: They are neutral particles present in the nucleus of an atom.
An atomic number is defined as the number of protons or number of electrons present in a neutral atom. It remains specific for a particular element.
Mass number is defined as the sum of the number of protons and neutrons present in the nucleus of an atom.
Given values:
<u>For isotope 1:</u>
Number of protons = 11 = atomic number
Number of neutrons = 13
Mass number = 11 + 13 = 24
<u>For isotope 2:</u>
Number of protons = 11 = atomic number
Number of neutrons = 12
Mass number = 11 + 12 = 23
As the atomic number of both the isotopes is the same. Thus, they belong to the same elements.
First, you mix the salt and sand with water, so the salt dissolves. Next, you filter the sand out, so you have the slat water and sand separated. Then, you evaporate the water, leaving the salt behind.
Answer/Explanation:
Heat from the sun hits the ground and is absorbed. The higher you go, it gets more colder due to the fact that the air doesn't hold onto the radiation as it goes straight through the ground, which is why the top of mountains are very cold, and people are able to die in minutes.
