Answer : The protons and neutrons subatomic particles will be located at Z.
Explanation :
In the model of an atom, there are three subatomic particles. Protons, neutrons and electrons are the subatomic particles.
The protons and the neutrons subatomic particles are located inside the nucleus and the electrons subatomic particle are located around or outside the nucleus.
The protons are positively charged, electrons are negatively charged and neutrons are neutral that means it has no charge.
In the given dartboard, Z is the nucleus in which the protons and neutrons subatomic particles are present and x, w & y are the electrons because they are located around the nucleus.
Hence, the protons and neutrons subatomic particles will be located at Z.
Answer:
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
Explanation:
if you are talking about the climate change of today as in the heat your answer would be ,because the green house gases are trapping in the heat and reflecting it back down it disrupts the temperature everywhere. so the hot weather will become even HOTTER the cold weather will become warmer of come to late ,and the places such as Greenland and Antarctica which are covered in snow will start to melt making the whole globe more hot year by year
Answer:
Cannot withstand very high temperature as all plastics melt down very soon as compared to metals
Answer : The correct option is, (a) lose electrons and form a positive ion
Explanation :
Metals : These are the elements that easily loose electrons and forms cations.
They require less energy to loose electrons because electrons are loosely bound to the nucleus.
Non-metals : These are the elements that easily gain electrons to form an anion.
They require more energy to loose electrons because the electrons are tightly bound to the nucleus.
As per question, when a metal reacts with a nonmetal, the metal will lose electrons and form a positive ion and non-metal gain electrons and form a negative ion.
Hence, the correct option is, (a)
