Is this an experiment? If so, if you have a small environment, compare it to a larger one, like your backyard for instance. Does the small environment have the same things as your backyard? Are they different? Compare them both like the backyard would have trees and with bird nests, and bushes, and all sorts of living organisms. More than your small environment would right? Your small environment gets the same nutrients as the large environment such as Carbon Dioxide, Sunlight, Water. Does your small environment have any animals or insects? You could use that as a comparison too.

I Hope This Helped!

Which statement about subatomic particles is true?

Kruka [31]

The correct statement about subatomic particles is Electrons are the subatomic particles with the smallest mass.

The mass of protons and neutrons which are considered as 1 unit of mass of atoms is approximately 1836 times the mass of the electron

$\boxed {\boxed {\bold {Further ~ explanation}}}$

Atoms are composed of 3 types of basic particles namely protons, electrons, and neutrons

The mass of this basic particle is expressed in units of atomic mass

This atomic unit uses the standard atomic mass, that is, the C-12 isotope

1 atom C-12 = 12 atomic mass units

1 atomic mass unit = 1/12 x mass 1 C-12 atom

1 unit of atomic mass = 1.66.10⁻²⁴

the mass of each basic particle in atomic mass units is:

electron mass = 9.11.10⁻²⁸

proton mass = 1.6726.10⁻²⁴

neutron mass = 1,675.10⁻²⁴

The proton mass is considered to be equal to 1 atomic mass unit and a neutron which is also considered to be equal to 1 atomic mass unit

The charge of 1 proton is equal to a charge of 1 electron but has a different sign

The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)

For a charge of 1 electron = e = 1.66.10⁻¹⁹ coulomb

Whereas the neutron charge = 0

Let's look at the answer choices

1. Protons are the only subatomic particles to have a charge.

This statement is wrong because in the nucleus there are electrons charged -

2. Electrons are the subatomic particles with the smallest mass.

The statement is true because the mass of protons and neutrons which are considered as 1 unit of mass of atoms is approximately 1836 times the mass of the electron

3. Neutrons orbit the nucleus of the atom.

This statement is wrong.

It can be explained by the Bohr atomic model, where electrons circulate the nucleus on a particular path so that electrons are not attracted to the nucleus.
