Atom: Exploration of 5 Types of Atomic Models

ATOM- In chemistry lessons, atoms also have several types of models. Wow, how many models are there? Curious? let’s just explore 5 types of atomic models!

As previously mentioned, there are 5 atomic models, including Squad. How come there are 5, huh? You can! The atomic model has developed over time. Starting from the simplest to the most sophisticated as it is today. Let’s start getting to know each other, shall we?

Dalton’s Atomic Model

The simplest atomic model is the Dalton atomic model, proposed by John Dalton, a British scientist. According to this model of the atom, the atom is a solid sphere with no charge. In addition, according to this atomic theory, the atom is the smallest unit that cannot be subdivided. Different chemical elements will have different types of atoms.

Thompson’s Atomic Model

The second atomic model is the Thompson atomic model. As the name … Read More

What Roles Do Diets Play In Your Social Life?

As the saying goes, “No man is an Island.” The interdependence of human beings is the major reason human interactions are important and cannot be overlooked.

People interact with other people in different ways, but one unifying factor in all human interactions is the need to feel a sense of belonging. In Maslow’s Hierarchy of Needs Theory, The need for love and belonging comes after the fulfillment of safety needs. Once a person feels safe, they begin to seek love and find a community to belong to.

A person’s social life is affected by many factors, and these factors go on to determine how the person navigates human relationships. On Collected.Reviews, users describe how some factors, like diet, have influenced their social life.

Also, people on the internet have a lot of opinions on diet regimes and the effects of these diet regimes on their lives, especially their social … Read More

Definition of Plant Breeding

Plant reproduction is a process that aims to increase the number of plant species or certain cultivars, in general, there are two types of plant reproduction, namely:
• Sexual reproduction
• Asexual reproduction
And in nature, almost all plants reproduce sexually by producing viable seeds.
Sexual reproduction
Sexual reproduction involves bringing together “male” pollen and “female” egg cells to produce seeds. A seed is composed of three parts, namely the seed coat as the seed protector, the endosperm as a food reserve, and the embryo which is a plant candidate. When the seeds have matured and are in a suitable environment, they will begin to germinate, which in general there are two types of sexual propagation, namely isogamy, and heterogamy.
Advantages and disadvantages
As for sexual breeding, there are advantages and disadvantages which include:
• Advantages
Plants grown through seeds in living conditions have a deep root system so that … Read More

The Arrangement of the Solar System

The Arrangement of the Solar System. The solar system is where a collection of celestial bodies consisting of the sun (stars), planets, natural satellites, meteors, asteroids, and also comets that will revolve around the sun or often called evolve.

The Arrangement of the Solar System. The sun is the center of the solar system because all celestial bodies will rotate around the sun with an elliptical trajectory. In each revolution, the members of the solar system at one time objects are close to the sun. The point closest to the sun is called the perihelium and also the farthest point is called the aphelion.

Some of the Benefits of Ultrasonic Sound

Some of the Benefits of Ultrasonic Sound. Definition of Sound
Sound is vibration. For example, pond water gurgles, the wind in the trees, and the sound of dogs barking.

Some of the Benefits of Ultrasonic Sound. So, the sound is vibration. However, not all vibrations can produce sound. There are some objects that are vibrating, but the sound cannot be heard. If the number of vibrations of an object per unit of time does not meet a certain number, the resulting sound cannot be heard.


Sounds whose frequency is less than 20 Hz cannot be heard by normal human ears. Sounds in this frequency area are called infrasound. Likewise, sounds with frequencies above 20,000 Hz.


The rate of sound propagation in the air at room temperature is approximately 340 m / s. Currently, there are many aircraft, especially the type of fighter aircraft that can fly at speeds … Read More

Vertebrate and Invertebrate Animal Groupings

Vertebrate and Invertebrate Animal Groupings. Vertebrates and invertebrates are two groups of animals with different structures in their bodies. There are so many animals that exist on this earth.
One of the ways to distinguish them is by looking at the structure of their bodies. Then what are invertebrates and vertebrates?

Vertebrates and Invertebrates

Vertebrate and Invertebrate Animal Groupings. There are many types of animals that exist on earth. Meanwhile, there are groups of animals that are divided into two based on the structure of their bodies.

Supermassive Black Hole At The Centre Of Milky Way Pictured For First Time

Because nothing can get out of black holes, physicists struggle understanding these objects. Not even the laws of physics tell us what happens when something falls into a black hole—at least not yet. Therefore, black holes remain cosmic mysteries, and many scientists work hard to solve the mystery of black holes. And by comparing these new observations with those of M87, researchers can learn more about how black holes of different masses behave. Finally there are the supermassive black holes that inhabit the centre of most galaxies. These are thought to arise relatively soon after their galaxies are formed, devouring enormous amounts of material to achieve colossal size.

The merging of both light and heavy seeds and the subsequent ingestion of more matter may then lead to a supermassive black hole. It is believed that one may exist at the centre of the Milky Way, as well as at the … Read More

Atoms, Elements And Compounds

Atoms consist of a nucleus surrounded by negatively charged electrons. Protons and neutrons are found within the nucleus (Figure created with BioRender.com). Letters from the alphabet are used to represent chemical elements. An element’s chemical symbol is a single capital letter or a capital letter followed by a lower case letter. Ethanol is a much larger molecule made of three types of atoms.

Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand the influences leading to the formation of an ionic bond we need to consider the electronic arrangement of sodium and chlorine atoms. Sodium structure is 2,8,1 with one electron in the outer shell.
