Answer:
covalent bond
Explanation:
ionic bond is when electrons are transferred by atoms not shared
How are covelant and ionic bonds different and what types of elements combine to form each?
Answer:
Ionic bonds result from the transfer of electrons from one atom to another
Explanation:
In covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged.Covalent bonds are formed between two non-metals, whereas ionic bonds are formed between a metal and non-metal.
Answer:
Covalent bonds are defined as sharing of electrons, ionic bonds are the result of transferred electrons;
Covalent bonds form between non-metals (elements) and ionic bonds form between metal and non-metals (ions)

methane is called an organic compound why
Answer:
Explanation:
1) Organic compounds always contain only p-block elements (Groups III-VII), at least one of which must be carbon. 2) Organic compounds almost always contain one or more C-H bonds. ... Thus, all bonds are typically covalent in organic compounds. Methane (CH4) is the prototypical organic molecule.
Methane contains carbon, forming covalent bonds, and is found in living organisms, making it an organic compound.
Methane (CH₄) is considered an organic compound due to its molecular structure and occurrence in living organisms. Organic compounds are primarily composed of carbon atoms covalently bonded to hydrogen and often other elements like oxygen, nitrogen, sulfur, and more.
Methane consists of one carbon atom bonded to four hydrogen atoms through covalent bonds. Carbon's unique ability to form stable covalent bonds with other elements, including itself, leads to the vast diversity of organic molecules found in living organisms.
Methane is a crucial component of natural gas and is produced by various biological and geological processes. It is present in the digestive systems of animals, formed during decomposition, and plays a role in carbon and energy cycles.
Its prevalence in living systems and its molecular structure classify methane as an organic compound, reflecting the foundational principles of organic chemistry.

which characteristic do valence electrons indicate about reactions between atoms?
Bond number
The characteristic of reactions that depends on valence electrons is the bond type.
In chemistry, a chemical bond could be;
Ionic
Covalent
The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.
When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

What is oxidation state?
Answer:
a number assigned to an element in chemical combination which represents the number of electrons lost (or gained, if the number is negative), by an atom of that element in the compound
Explanation:
sodium, magnesium, iron is zero.
The definition of oxidation state is as follows: Oxidation state is a number given to the atom of an element when participating in a chemical reaction.
OXIDATION STATE:The atoms of elements are not always neutral i.e. carry no charge. They sometimes carry either positive or negative charges to become ions. Ions can either be cations (positively charged) or anions (negatively charged). The amount of charges are represented by numbers placed as a superscript in front of the element involved. These superscript charge assigned to a corresponding element during a chemical reaction is called oxidation state. The oxidation state of an element portrays the number of electrons gained or lost during the reaction.Therefore, oxidation state can be defined as a number given to the atom of an element when participating in a chemical reaction.

What is covalent bond?
Covalent bond is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.
Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.
Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.
