How to I find the number of electrons in and Atom?

Chemistry

Inessa [10]3 years ago

Look at the atomic number of an element on the periodic table which is the smaller number.
The atomic number shows the number of protons/electrons so the number of protons and electrons are the same.
Whereas the mass number of an element (the other number) is the number of protons + neutrons.

Answer:

Explanation:

The Key results in the Lab guide are results that justify the reasons to either accept or reject a hypothesis.

To summarize data related to findings in an experiments we make use of diagrams that shows the relationship between the different data.

Although the Lab guide in the question is missing a general answer within the scope of your question is provided above

Key results in an experiment are either milestone results leading to the final result of an experiment or results obtained that might not be part of the experiment but very important to the success of the experiments. therefore results that leads to the acceptance or rejection of a hypothesis in an experiment is a key result.   while

The best way to summarize data related to findings is the use of diagrams. ( graphical representation of the relationships between data contained in an experiment )

Hence we can conclude that use of diagrams is the best way to show the relationship between different data related to experimental findings while key results are results that justifies the acceptance of a hypothesis.

A solid piece of lead has a mass of 23.94g and a volume of 2.10cm^3. from these data, calculate the density of lead in si units
jeyben [28]
A density of a substance is constant. It is an extensive property, meaning it does not depend on the amount of substance because it is a ratio of mass to volume. No matter how much of each there is, they would always have a fixed ratio called density. For lead, the density is

Density = mass/volume
Density = 23.94 g/ 2.10 cm³
Density = 11.4 g/cm³

There are many compounds that contribute to the overall aroma of a banana. The primary compound is called isoamyl acetate and co
Murljashka [212]

Explanation:

Let the mass of isoamyl acetate be 100g.

Moles of Carbon = 60.58/12 = 5.048mol

Moles of Hydrogen = 7.07/1 = 7.07mol

Moles of Oxygen = 32.28/16 = 2.018mol

Mole Ratio of C : H : O

= 5.048 : 7.07 : 2.018

= 5 : 7 : 2.

Hence the empirical formula of isoamyl acetate is C5H7O2.
