Answer:

Option A) Atoms have lost or gained an electron and have a charge

Explanation:

The result of a loss or gained electron can cause a large or lesser number of protons than the electrons, which causes a charge imbalance because protons have a positive charge and electrons have a negative charge.  If the number of protons or the number of electrons is unequal, then it means that the atom has a charge, and is an ion.  It is a cation if it lost an electron such that it has a positive charge and it is an anion if it gained an electron such that it has a negative charge.

212 pb 82 is the isotope notation for iron. what is the atomic number, mass number, and number of both protons and neutrons?
o-na [289]

Hello!

The mass number in isotope notation is denoted A, the atomic number is denoted as Z, and the element is denoted as X.

In the given isotope, the mass of the isotope is 212 amu, and the atomic number is 82.

We know that the number of electrons, and protons are equal to the atomic number. Therefore, there are 82 protons. Also, to find the number of neutrons, we subtract the atomic number from the atomic mass.

212 - 82 = 130 neutrons

<u>Final answers</u>:  

  1. Atomic Number: 82
  2. Mass number: 212
  3. Number of Protons: 82
  4. Number of Neutrons: 130

Which of the following is considered a drawback to using wind energy as a source of power?
Olin [163]

Answer:

Option (3)

Explanation:

Wind energy is directly derived from the wind. In the places where wind blowing is quite frequent, there wind mills are being set up, and the turbines in it rotates due to the prevailing wind. Due to this continuous motion of turbines, it collects the wind energy and it is being transferred into electrical energy.

It is cost-effective and does not produce any kind of pollution and is completely a renewable energy, that it can generated again and again.

It does have certain drawbacks also, because <u>the area may sometime do not experience constant wind, due to which it cannot store energy. So frequent wind blowing areas are the best place to set up windmills</u>.

Thus, the correct answer is option (3)
