What are the symbols, atomic mass and abundance in nature of the isotope boron-11
Aneli [31]
  1. The chemical symbol of the isotope boron-11 is ¹¹B.
  2. The atomic mass of the isotope boron-11 is equal to 11.009306.
  3. The abundance in nature of the isotope boron-11 is equal to 80.1%.

<h3>What is an isotope?</h3>

An isotope can be defined as the atom of a chemical element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of neutrons).

In Chemistry, there are two main isotopes of boron and these include the following:

  • Boron-10
  • Boron-11

Boron-11 is the most stable isotope of boron and it is characterized by the following:

  1. The chemical symbol of the isotope boron-11 is ¹¹B.
  2. The atomic mass of the isotope boron-11 is equal to 11.009306.
  3. The abundance in nature of the isotope boron-11 is equal to 80.1%.

It is possible to prepare ethanol by nucleophilic substitution. For an electrophile, you could choose EtCl, EtBr, or EtI; for a
tensa zangetsu [6.8K]

Answer:

The reactant/reagent that would be most atom economical is EtI (Ethy Iodide) and KOH (potassium oxide) as base

This is because the iodo group are weak base hence they have a good leaving character (i.e they are unstable on their own ) which would increase the rate of reaction and the strong base KOH give the most atom economical

These statements describe three different reactions.
Naily [24]

An atom gains an electron from another atom. Hence, option B is the correct answer.

<h3>What is an atom?</h3>

An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons.

When an atom shares electrons with another atom then it results in the formation of a covalent bond.

Whereas when an atom transfer electrons from one atom to another then it results in the formation of an ionic bond.

When the nucleus of an atom splits then it represents a nuclear fission reaction and energy is released during this process.

Hence, option B is the correct answer.
