The types of bonding are called ionic, molecular covalent, metallic, and network covalent. I’m not sure about the second part of the question.
<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.
Answer:
a) significant figures b) decimal places
Multiplying/dividing ex: 1.33 * 4.4932 = 5.98 because the first component only has three sig figs while the second has five.
Adding/subtracting ex: 12.13 + 53.5763 = 65.71 we ignore the whole numbers and focus only on the decimal places. The first component only has two while the second has four. Hope this helps!

Greenhouse gases absorb and emit some of the outgoing energy radiated from Earth's surface, causing that heat to be retained in the lower atmosphere. As explained above, some greenhouse gases remain in the atmosphere for decades or even centuries, and therefore can affect Earth's energy balance over a long period.
