An ionic compound is a compound between a metal and a non metal where the metal (normally from group 1 or 2) transferrs an electron to the non metal ( most commonly from group 6 or 7) . this is so that both atoms have a full outer shell of electrons. the metal gains a positive charge and the non metal a negative charge. they are held together by electrostatic forces of attraction. an example would be sodium chloride (salt) sodium is in group 1 and chlorine in group 7 so sodium transfers one electron :)
Hydropower is electricity generated by harnessing the energy of moving water. This kind or energy provides almost one fifth of the world's electricity.
Below is the mechanism showing the hydrolysis of Iminium Ion into aldehye. The arrows are shown in RED.
Answer:
Protons Neutron Electrons
hydrogen-1 1 0 1
hydrogen-2 1 1 1
hydrogen-3 1 2 1
Explanation:
hydrogen-1, hydrogen-2, and hydrogen-3 are all isotopes.
Isotopes have the same number of protons but a varying number of neutrons. Protons = Electrons.
Answer:
s<p<q<r
Explanation:
Given
Element s displaces p from its oxide. Thus, s is more reactive that p
p reacts with cold water but element q cannot react with cold water. Thus,
p is more reactive than q
Element q is able to react with weak or dilute acids but element r in unable to react with weak or dilute acids. Thus, q is more reactive that r
The order of four elements on the basis of their reactivity in descending order is as follows
s<p<q<r
