Why does the reactivity of metals increase from right to left on the periodic table? (1 point)
Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced,
Metals on the right have more protons, causing valence electrons to be held more strongly
Metals on the right have fewer protons, making it harder to attract electrons from other atoms,
Metals on the right have fewer valence energy levels, so electrons are closer to the nucleus and harder to pull away

Answers

Taking into account the definition of reactivity, the correct option is the first option: Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.

Reactivity is a measure of the probability that a chemical species will participate in a chemical reaction to form chemical bonds.

In other words, the reactivity of a chemical element is the tendency that this element has to combine with others.

For elements that behave like metals, this trend is directly related to the ease with which they lose their valence electrons.

Valence electrons are those electrons farthest from the nucleus of the atom. These electrons are easier to remove because they are the least attracted to the nucleus. Thus, less and less energy is needed to start these valence electrons, so they can commonly participate in the formation of chemical bonds.

In other words, as the size of the metal atoms in a group increases, so does their reactivity.

Then, the correct option is the first option: Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.

Be.
•As.
A. 1:3
B. 2:1
C. 3:2
D. 1:1

Answers

Answer  the ratio of Be to At is 1:2 in the compound

Explanation:

Be in Periodic Table 2A has 2 valence electrons in its outer orbital and needs to give them away.  When it gets rid of 2 negatives, its charge is +2.

At in Periodic Table 7A has 7 valence electrons in it outer orbitals and needs one more electron.  2 AT atoms each accept one electron from Be and each has a charge of -1.  The Be ion of +2 charge is balanced by the two At ions of -1 charge, so the ratio of Be to At is 1:2

The situation in which the generator is able to produce more electricity is option D, the average height of each wave increases.

What is water wave?

Water wave is a type of mechanical wave. Water wave is a transverse wave in which the oscillation of particles is along the direction of wave propagation.

The the water waves are highly energetic and this kinetic energy is converted to electric energy using turbines and generator. The height  to the crest of the wave from the base line is called amplitude. As the amplitude increases, energy of the wave is increasing.

Thus, more the amplitude, more the energy of wave leading to greater yield of electrical energy as well. Therefore, option D is correct.

While considering boiling point elevation and freezing point depression a solution concentration is expressed in molality and not in molarity?why?

Answers

Answer:

Colligative properties are physical properties of solutions, like boiling point elevation and freezing point depression. In these calculations, the temperature of the solution is changing as we add more solute to the solvent, so this means that the volume of the solution is changing. Since molarity is moles solute per liter of solution, we cannot use molarity as our concentration unit. This is why we use molality (moles solute per kg of solvent) since the kg of solvent doesn't change with temperature.

Explanation:

First in boiling point elevation and freezing point depression, we deal with the system whose temperature is not constant.   Second we cannot express the concentration of the solution in mortality because it changes with temperature whereas mortality is temperature independent.  Therefore, while considering boiling point elevation and freezing point depression a solution concentration is expressed in mortality and not in mortality.

How do valence electrons impact the type of bonds an atom makes?

An atom wants an empty outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.
A large number of valence electrons means the atom will share electrons; a small number of valence electrons leads to transferring from one atom to another.

Methane’s chemical formula is CH4. Is there a bond between any of the hydrogen atoms? Why or why not?
Yes, there is because there are one too many hydrogen atoms for carbon to handle alone, so one hydrogen must bond with another.
No, there is not because carbon needs four bonds, so it bonds with each hydrogen atom; hydrogen only forms one bond.
No, there is not because it would form H2 instead of methane if hydrogen bonded with itself.
Yes, there is because they form a long chain in order to all have stable outer energy shells.
