To understand why an atom as a whole is electrically neutral, we can break down the explanation into several steps:1. Identify the Subatomic Particles: - An atom is made up of three types of subatomic particles: protons, ne
An atom is normally electrically neutral. Why, then, should an alpha particle be deflected by the atom under any circumstances?Alpha ParticlesAlpha particles are made up of 2 protons and 2 neutrons. A proton has a +1 charge while a neutron ...
Why are ionic solids hard?Question:Why are ionic solids hard?Table Salt:One of the most common chemicals that is seen in an average household is table salt. Nearly 99% of table salt is sodium chloride, but it often contains additives that are added before packaging. Regular table salt has...
Why do substances expand when the temperature is increased? Helium and lithium are two elements that differ only in one electron. Why do you think they exhibit such different chemical and physical behavior? Why our mass reduces on the moon? Why does dark matter not interact with normal matter?
Assertion : Atom is electrically neutral. Reason : A neutral particle, neutron is present in the nucleus of atom. AIf both assertion and reason are true and reason is the correct explanation of assertion. BIf both assertion and reason are true but reason is not the correct explanation of asse...
Answer and Explanation:1 When left to themselves, a DVD and cloth are electrically neutral. When you rub them together, however, in the act of wiping, electrons are... Learn more about this topic: Static Electricity Lesson for Kids: Definition & Facts ...
The heavier elements are those elements whose atomic number or the number of proton in their nucleus are greater than 92. However, the lighter element is those less than 92. Usually, the heavier elements are unstable because of high internal energy due to nuclear forces, consequently, the ...
Considering the work of J. J. Thomson, which particles are most important in the formation of compounds and why?Subatomic ParticlesThe fundamental unit of matter (atom) is composed of subatomic particles: neutrons, protons, and electrons. Neutrons are neutr...
Why do some substances not dissolve in water at all? Why is the ionic compound NaCl (table salt) able to dissolve in a glass of the molecular compound water (H_2O)? Why are most solid ionic compounds electrically non-conductive, whereas aqueous solutions of ionic compounds are good conduc...
How come two non-polar substances are able to easily mix? Describe what kinds of particles or matter you think quarks might be made of. Research is not necessary for this; use your imagination plus logic to arrive at your answer.
