The density of a material is a/an ___________.
Nitella [24]

The density of a material is an intensive property.

<h3>What is intensive property?</h3>

An intensive property of matter is one that does not change with the amount of matter. It is a bulk property, which means that it is a physical property that is independent of sample size or mass. An extensive property, on the other hand, is one that is affected by sample size.

<h3>What factors influence an intensive property?</h3>

Intensive properties are those that are determined solely by the characteristics of the material and not by its quantity - for example, density, temperature, refractive index, color, and pressure. Intensive properties are not additive, which means their value does not change when the amount of material is changed.

Explain how to use the periodic table to deduce the number of protons, neutrons and electrons of an atom of a specific element
Ksju [112]

Answer:

See explanation

Explanation:

The periodic table shows the atomic number and mass number of each element.

We know that the atomic number shows;

  1. The number of protons in the nucleus of the atom
  2. The number of electrons in the neutral atom of the element.

So we obtain the number of protons and electrons by looking at the atomic number shown in the periodic table.

We also know that;

Mass number = Number of protons + number of neutrons

Since number of protons = atomic number of the atom

Number of neutrons = Mass number - atomic number

Hence we obtain the number of protons by subtracting the atomic number from the mass number given in the periodic table.
