Are most elements on the periodic table nonmetals?
Answers
Final answer:
No, most elements on the periodic table are not nonmetals. About 75% of the elements on the periodic table are metals, with nonmetals including the Noble Gases, Halogens, Nitrogen and Oxygen making up a smaller portion. Additionally, the Metalliods, which are elements with properties of both metals and nonmetals, also hold a place on the periodic table.
Explanation:
No, most elements on the periodic table are not nonmetals, but rather metals. The periodic table is primarily comprised of metals, with the so-called 'metal' elements making up about 75% of the table's total elements. Nonmetals count for only a small part, located on the right side of the table. They include the Noble Gases, the Halogens, and some others like Nitrogen and Oxygen
Furthermore, there are a group of elements known as the Metalliods or Semi-Metals which have properties in between metals and nonmetals. These are located in a diagonal line from Boron to Astatine.

Answer:
The arguments that could be used to challenge the idea of using wind power to provide electricity to the whole country is that there is a difficulty in capturing wind, wind power causes visual and sound impacts, as well as an impact on fauna.
Explanation:
Wind energy is a widely used method for obtaining power through wind power, which drives windmill and windmill-like mechanisms connected to a generator that produces electricity.
The main advantage of wind energy is that it is considered a clean energy, that is, obtained from renewable sources and without generating any kind of polluting waste during its production and consumption.
Although wind energy is one of the best options for obtaining energy from renewable and clean sources, it is possible to see some negative points of this technique. These negative points are:
- Difficulty catching wind: Because it is totally dependent on wind and air currents, it is possible that an unfavorable climate will compromise production;
- Visual Impact: The installation of wind turbines can cause major changes in the landscape, either due to the space required to install the equipment or the size of the necessary mechanisms;
- Animal Impact: Modifications related to the installation of wind energy equipment change the habitat of several animals, especially migratory birds, so that they have to adapt;
- Sound impact: Wind energy production is very noisy, which can frighten animals and disrupt the daily lives of people living in areas near the wind farm.

Answer:
A solid will melt at the temperature at which the kinetic energy breaks theinter-molecular attractions.
Explanation:
The melting point is the state at which "a substance changes its temperature from a solid to liquid". At the melting point temperature, there is an equilibrium between the both the solid and the liquid phase. When the solid particle is heated by increasing the temperature the particle in the solid vibrate quickly and it absorbs kinetic energy.
It leads to the breaking of the organisation of particle in between the solid and that leads to the melting of solid. Thus, at the melting point, the kinetic energy breaks the inter-molecular attractions.
Answer: B) the temperature at which the kinetic energy breaks the intermolecular attraction
