After an ionic bond is formed, what is the charge of the atom that gained an electron?

Answers

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.

What are tectonic plates?

A tectonic plate (also known as a lithospheric plate) is a huge slab of solid rock that is made up of both continental and oceanic lithosphere. Plate size can range from a few hundred kilometers to hundreds of kilometers; the Pacific and Antarctic Plates are among the largest tectonic Plates.

The majority of volcanoes and earthquakes form at the tectonic plate boundaries of the Earth. These plates are massive slabs of the Earth's crust and upper mantle that fit together like puzzle pieces.

Tectonic plates are fragments of the crust, the Earth's rocky outer layer. Volcanoes and earthquakes can be found along plate boundaries because these plates are continually shifting.

Therefore, the correct option is b. Earthquake and volcanic activity are evident.

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.

1. How do you think rapid changes in the chracteristics of habitats affect the niches of
animals occupying that habitat?

Answers

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.

Answers

D both can be used as sources of energy

The similarity between lipids and carbohydrates is that both are classes of chemical compounds that are found in living things. Thus, option D is correct.

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.

Therefore, Both lipids and carbohydrates can be used by the cell as sources of energy.
