Answer;

Sodium (Na)

A single sodium atom has 11 protons, 11 electrons, and 12 neutrons.


Explanation;

For any neutral atom, the number of protons is the same as the number of electrons. If an atom loses or gains electrons, it is called an ion.

A sodium atom contains 11 protons, so its atomic number is 11. Mass number is the total of the protons and neutrons together, thus sodium has a mass number of 23.

HELP I NEED A SCIENTIFIC MODEL AND PARAGHRAPH ABOUT ATOMIC THEROY WILL GIVE BRANLIEST AND POINTS
saveliy_v [14]

<h2>Atomic Theory:</h2><h2>Introduction</h2>

The atomic theory of Atoms Summed up is the idea that all matter is made of tiny particles that are imperceptible to the mortal eye; these particles are named Atoms

<h2>Paragraph 1:</h2>

John Dalton was the first to consider that all matter was made of tiny particles known as atoms. He invented the idea that matter is formed of atoms varying in weight.

<h2>Paragraph 2:</h2>

I created this model of the dissimilarities between three kinds of matter-- solids, liquids, and gases. The distance between atoms in each state tells us what type of matter we observe.

The Drawing is on the file

The End.

What is meant my urbanization and industrialization? How they degrade the environment ​
Whitepunk [10]
Urbanization is defined as “the process of making an area more urban” or an increase in the amount of people living in towns or cities. Industrialization is defined as “the development of industries in a country or region on a wide scale” meaning a strong military with modern weapons, factories to create things, modern cars and boats etc. Urbanization and industrialization put a strain on the environment because of carbon gases emitted, effectively warming the earth up, destruction of trees which lowers our overall oxygen available, destruction of animal homes which will kill animals or cause unwanted interactions between humans and animals, and the pollution of natural resources such as local ponds, streams or the ocean.
