Rutherford's gold-foil experiments proved the existence of which of the following?

Chemistry

Anestetic [448]3 years ago
4 0
The answer is the nucleus, because the beam of alpha particles would hit a small, dense positively charged center (nucleus) in the gold foil and bounce back or deflect at angles.

Humans depend on water from various sources for different reasons. All of these sources are polluted or could be polluted to som
goldenfox [79]

Explanation:

Earth is known as the "Blue Planet" because 71 percent of the Earth's surface is covered with water. Water also exists below land surface and as water vapor in the air. Water is a finite source. The bottled water that is consumed today might possibly be the same water that once trickled down the back of a wooly mammoth. The Earth is a closed system, meaning that very little matter, including water, ever leaves or enters the atmosphere; the water that was here billions of years ago is still here now. But, the Earth cleans and replenishes the water supply through the hydrologic cycle.

Highlight the basic points in Lewis and Langmuir theory of electrovalency
ankoles [38]
The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges. 

The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds. 

Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas

<span>The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.</span>

Which of the following elements has the strongest ionization energy: Mg or Cl? Define ionization
Mila [183]

Answer:

Cl

Explanation:

The element Cl will have the strongest ionization energy from the given choices. Most non-metals have higher ionization energy compared to metals.

Ionization energy is the energy required to remove the most loosely held electron from the gaseous phase of an atom.

  • As you go from left to right on the periodic table, it increases progressive
  • From top to bottom, the ionization energy reduces significantly.
  • The attractive force between the protons in the nucleus and the electrons plays a very important role.
  • In metals, they have very large atomic radius, the attractive force on the outer electrons is very weak.
  • This is not the case in non-metals

What is the correct ionic formula when mg2+ and p3− react?
Mumz [18]

Answer: Ionic formula will be Mg_3P_2.

Explanation: Mg^{2+} and P^{3-} ions will form a ionic compound. Ionic compounds have both metals and non-metals.

Here Mg^{2+} is a metal and P^{3-} is a non-metal.

The net charge on any compound must be 0.

So we need 2 phosphate ions to balance the charge on Mg^{2+} ions. Similarly we need 3 Magnesium ions to balance the charge on P^{3-} ions.

Criss-crossing the charges, we will get the formula as Mg_3P_2

Criss-crossing is shown in the image below.
