Galvanic and electrolytic cell are both types of electrochemical cells that involve the conversion of chemical energy into electrical energy, but they operate in opposite directions. Here are some similarities between galvanic cells and electrolytic&hellip
What is Valency? The property of the atoms of an element to be chemically bonded to an exact number of atoms of other elements is called valency. Valency is an integer that shows how many&hellip
This is a question that always hinders us initially in our Chemistry class. All that talk of electrons, ions and valence shells has our head spinning! In reality, the concept is quite easy. For simplicity,&hellip
Electronegativity refers to a property of particles and atoms that make them attract electrons or particles that are negatively charged. There are various elements and particles present in the Earth, and each of them are&hellip
Cations are atoms that contain a positive charge, and they are formed when the atoms lose electrons which are negatively charged. This is the typical behavior for many metal substances. And because of this behavior,&hellip
An atom is considered the most basic unit of matter, and it is considered neutral or neutrally-charged simply because it contains the same numbers of protons and electrons. Â Protons and electrons have opposite charges, but&hellip
The wire will become hot as it is smaller to pass the rated current inside. Any wire will not have zero resistance. The resistance might be near to nil but not totally nil. If current&hellip
Why Do Positive and Negative Ions form? Atoms have nucleus which includes protons and neutrons. The space that is outside the nucleus of every atom is occupied by the electrons. The electrons are present in&hellip
Why do Metals lose Electrons? As the elements span from left side to right side of the periodic table, the elements become more electronegative and they get more stabilized and attain the characteristic features of&hellip
Why is Second Ionization Energy higher? Ionization energy refers to the amount of energy needed for a number of electrons to be removed from a single atom. Measured using the unit called the electronVolt and&hellip
Why do Nonmetals gain electrons? Metals have very few electrons in their outer atomic shells and non-metals have more electrons in their valence shells and hence will tend to fill up the small gap in&hellip
Why is Atomic mass a decimal? Atomic mass is the total weight of a single atom that is comprised of the number of protons, electrons and neutrons. Most commonly expressed in unified atomic mass units&hellip
Why is NH4 positive? If ammonia (NH3) is neutral then it must have equal numbers of protons and electrons. If a proton is added to ammonia, the resulting NH4+ will have an extra proton. Hence&hellip
