How many protons, neutrons and electrons are there in a neutral atom of the isotope of lithium named lithium-6?

1 answer:

4 0

Well first of all the atomic mass is the number of protons + the number of neutrons this is the mass of the nucleus and meaning that the protons and neutrons make up the nucleus which is where all the mass is located. So the number of protons will be equal to the number of electrons if it is a neutral atom. So the atomic number of Lithium is 3 and this is equal to the number of protons. So if you want to find the number of neutrons you have to subtract the number of protons which in this case is 3, so you're going to subtract 3 from 6 (6-3) and this is going to leave you with 3 neutrons. So in this case there are 3 Protons, 3 Neutrons, And 3 Electrons.

What is rate of reaction? Discuss in brief slow and fast reactions.

Sindrei [870]

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

Reactions that happen quickly have a high rate of reaction. For example, the chemical weathering of rocks is a very slow reaction: it has a low rate of reaction. Explosions are very fast reactions: they have a high rate of reaction. Rate of reaction is an example of a compound measure.

How to classify hemicetal and acetal

kumpel [21]

You might have meant hemiacetal, not hemicetal.
Acetals contain two –OR groups, one –R group and a –H atom. In hemiacetals, one of the –OR groups in acetals is replaced by a –OH group.
