what are two conditions atoms must have in order to form covalent bonds with one another

Answers

Answer 1
Answer: Covalent bonds are formed mainly between two non metals as electrostatic or ionic bond is prevented from being formed take the example of methane or CH4 (4 means four atoms of hydrogen) in this covalent bonding one atom of carbon combines with four atoms of hydrogen carbon also forms a large number of compounds or more commonly called hydrocarbons due to its property called catenation here hydrogen wishes to gain one electron to obtain duplet atomic structure of helium its closest noble gas element and carbon requires eight electrons in its outermost shell to attain a stable electronic configuration therefore carbon give one electron to each of the four hydrogen atoms and hence hydrogen attain the duplet electronic configuration having two electrons in its outermost shell and carbon loses four electrons from its outermost shell and four hydrogen atoms gain one electron from carbon forming methane covalent bond

Explanation:

Hydrogen peroxide

Hydrogen peroxide is a chemical compound with the formula H₂O₂. In its pure form, it is a very pale blue liquid, slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic. Concentrated hydrogen peroxide, or "high-test peroxide", is a reactive oxygen species and has been used as a propellant in rocketry. Its chemistry is dominated by the nature of its unstable peroxide bond.

Chemical formula: H2O2

Density: 1.45 g/cm³

Boiling point: 302.36°F (150.20°C)

Average Molar mass: 34.01 g/mol

Melting point: 31.23°F (-0.43°C)

Legal status: Over-the-counter drug · Not evaluated by FDA

Water

Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H₂O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Two hydrogen atoms are attached to one oxygen atom at an angle of 104.45°.

Boiling point: 212°F (100°C)

Melting point: 32°F (0°C)

Chemical formula: H2O

Average Molar mass: 18.02 g/mol

IUPAC ID: Water

What is protein?

Proteins are very large molecules made of basic units known as aminoacids. Proteins consist of carbon (C), hydrogen (H), nitrogen (N), oxygen (O), and sulfur (S).

Protein molecules are produced by twisted and folded strands of amino acids. Proteins are actively involved in the most important as well as basic aspects of life. These include metabolism, cellular communication, movement, molecular recognition, and defense.

The shape of structural proteins allows them to form essential structures of the body. Collagen holds most of the body tissues together, a protein with a fiber shape. Structural protein Keratin creates a network of waterproof fibers on the outer layer of the skin.

The shape of functional proteins enables them to contribute to the chemical processes of the body. Functional proteins include cell membrane receptors, hormones, growth factors, and enzymes.

Select all the correct images.Select the two atomic models that belong to the same element.

Answers

Answer : The atomic models that belongs to the same element are atomic model 2 and 3. (Shown below)

Explanation :

As we know that an atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.

The protons and the neutrons are located inside the nucleus or center of the nucleus where the mass of the an atom is concentrated and the electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Same element has same number of protons.

Atomic model 1 : In this model, there are 8 number of electrons, 8 number of protons and 8 number of neutrons.

Atomic model 2 : In this model, there are 5 number of electrons, 5 number of protons and 6 number of neutrons.

Atomic model 3 : In this model, there are 5 number of electrons, 5 number of protons and 5 number of neutrons.

Atomic model 4 : In this model, there are 6 number of electrons, 6 number of protons and 6 number of neutrons.

From this we conclude that, the atomic model 2 and 3 has same number of protons. So, these two models belongs to the same element.

Hence, the atomic models that belongs to the same element are atomic model 2 and 3. (Shown below)
