(0.5)HISTORY OF ATOM- Antimony explains

Learn with Antimony.

Hmm. After many years I met Niels Bohr.

Niels Bohr told me he agreed with the planetary model of

the atom, but also knew that it had a few

flaws.🤔 Using his knowledge of energy and

quantum physics he was able to perfect

Rutherford’s model. He was able to answer

why the electrons did not collapse into the

nucleus.☺

BOHR’S ATOMIC MODEL (AKA THE RUTHERFORD-BOHR MODEL) I think it was just modification of Rutherford experiments😋

This was the experiment Rutherford Carried out, where he fired alpha particles at gold foil

This includes that:

1. Electrons orbit the nucleus in orbits that have a set

size and energy.

2. The lower the energy of the electron, the lower the

orbit.

3. This means that as electrons fill up the orbitals, they

will fill the lower energy level first.🤔

4. If that energy level is fill (or at capacity), a new

energy level will begin.

5. Radiation is when an electron moves from one level to another.

Problems with this theory:

Electrons do not travel on a specific orbit or path.😴😴 .

This was one of the questions other great scientist keep on asking Bohr. (Bohr self try. E no easy jire😐

This was where he drew the curtain of his experiment. Let's check out the new model after MV Bohr' own in (0.6) next post

GENE- Antimony explains

What is gene? Hmm. Sounds weird. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes. Every person has two copies of each gene😮, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.🤔 Scientists keep track of genes by giving them unique ...

CHROMOSOMES- Antimony explains

What is a chromosome? In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.😮 Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division. Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific g...

John Dalton😋 Around 1800 BC. my friend then was John🙂 John Dalton was the first to adapt Democritus’ theory into the first modern atomic model. According to John: 1. All matter consists of tiny particles called atoms 2. Atoms are indestructible and unchangeable 3. Elements are characterized by the weight of their atoms 4. When elements react, it is their atoms that have combined to form new compounds I hope you dey grab😋 By: Oshinowo Testimony Antimony😎
