where are neutron founded?
Answer:
By 1920, physicists knew that most of the mass of the atom was located in a nucleus at its center, and that this central core contained protons. In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.
Explanation:
Answer:
In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.
Explanation:
Neutrons come from fusion. Let's say you push two protons together enough for them to "touch", specifically for them to experience attraction from the strong nuclear force that is stronger than electrostatic repulsion.You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there.
3. Approximately when was
the Moon full?
Answer:
When the Sun and the moon directly align.
Explanation:
At Full Moon, the entire face of the Moon is illuminated by the Sun's rays and it can be bright enough to light up otherwise dark nights.
Technically, this primary Moon phase only lasts a moment, the instant when the Sun and the Moon are aligned on opposite sides of Earth (see illustration). So the exact time for Full Moon is during the day on parts of the planet.
However, the Moon can appear to be full a day before or after while more than 98% of the Moon's disc is illuminated.
Therefore, it can be difficult to tell the difference between a Full Moon and the last stage of a Waxing Gibbous Moon or the beginning of a Waning Gibbous Moon.

1. How do you think rapid changes in the chracteristics of habitats affect the niches of
animals occupying that habitat?
Answer:
The rapid changes would make an organism change their land, environment around them, and the food web
When the habitat of the animals living in it changes, both the animals and the habitat change. It changes the biotic and abiotic factors of the niche and ecosystem. Habitat is part of a niche.
What is the impact of the changing habitat?
Niche is a broad space in which the particular animal roams, searches for food, and reproduces, but habitat is a part of the niche where the animal spends most of its life. Human interventions, such as cutting down forests for industry, roads, and so on, have an impact on wildlife. Due to this, the temperature of the earth keeps on increasing, resulting in climate change, global warming, the melting of ice, a rise in water levels, etc.
If these changes happen, then animals will have difficulty living in their habitat. The environment will not be favorable for living, and both abiotic and biotic factors will be disturbed, such as the fertility of the soil, which is affected by fewer trees. Other animals affect by this change too.
Hence, in this way, the change in habitat changes the niche.

What are the use of lipid and carbohydrate?Two of the four significant biomolecules include lipids and carbohydrates. They are both sources of energy.
However, although lipids store energy for later use and release it more slowly, carbs are available as instant energy sources. Thus, this is the primary distinction between lipids and carbs.
More energy is stored in lipids than in an equivalent mass of carbs. To release their energy, however, carbohydrates are easier to digest than lipids.
This indicates that they are made up of many carbon atoms with bonds to oxygen and hydrogen.

After an ionic bond is formed, what is the charge of the atom that gained an electron?
Answer: Negative
Explanation:
This is called an anion. Whenever an atom gains a electron, it becomes negative. When an atom loses an electron, it becomes postitive. Positive atoms are called cation.
After an ionic bond is formed, the charge of the atom that gained an electron will be negative.
What is an ionic bond?An ionic bond, also widely recognized as an electrovalent bond, is a category of interconnection established by the electrostatic attraction of ions with opposing charge in a chemical substance.
When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond is formed.
An ionic bond is formed between a metal and a nonmetal, whereas a covalent bond is formed between two nonmetals.
An ionic bond is formed by the complete transfer of electrons from one atom to another. When an atom loses one or more electrons, it becomes a cation, or positively charged ion.
When an atom gains one or more electrons, it becomes an anion, a negatively charged ion.
Thus, the atom is negatively charged as it gained electron.
