What else can I help you with?
What type of bond is PbO2?
An ionic bond.
What type of bond is carbon disulfide?
Carbon disulfide is a polar covalent bond due to the difference in electronegativity between carbon and sulfur.
If an element gains electrons what type of oxidation number does it have and how do you know?
If an element gains electrons, it has a negative oxidation number. The oxidation number is determined based on the number of electrons gained or lost by an atom in a compound. The rule is that in ionic compounds, the oxidation number of an element is equal to the charge it would have if it were an ion.
Type of atom in the compound is shown by number called?
Oxidation Numbers
The elements what determines how the compound will be formed?
The elements present in a compound determine how it will be formed based on their chemical properties, such as valence electrons, electronegativity, and reactivity. Elements will combine in specific ratios to achieve a stable configuration, following principles such as the octet rule and minimizing energy through bond formation. Factors like bond polarity, ionization energies, and electron affinity also influence how elements combine to form compounds.
How an element gets an oxidation number?
An element's oxidation number is determined based on its electron configuration and the number of electrons it gains or loses when forming chemical bonds. The rules for assigning oxidation numbers depend on the type of element and the chemical compound in which it appears. Oxidation numbers help to track the flow of electrons in chemical reactions.
What type of bond is likely to form from iron and sulfur?
An ionic bond is likely to form between iron and sulfur, where iron will donate electrons to sulfur to achieve a stable electron configuration. This results in the formation of iron sulfide, with iron typically having a +2 oxidation state and sulfur having a -2 oxidation state.
What type of bond can two cysteine form?
Two cysteine residues can form a covalent bond called a disulfide bond by oxidation of their thiol groups. This bond contributes to protein structure and stability, forming bridges between different regions of a protein or between different protein molecules.
What does oxidation number for an element tell you?
The oxidation number of an element tells you the charge that the element would have if electrons were transferred completely during the formation of a compound. It can help to determine the type of chemical reactions that an element is likely to undergo.
Is an oxidation number the same as the type of ion formed?
The overall oxidation number of an ion is indeed the charge. Na+, sodium is +1 ON, Cl-, chlorine is -1 ON. For a polyatomic ion the charge is the sum of the oxidation numbers of the consituent atoms. For example NH4+ ; N is -3, H is +1 so overall ON is +1 same as the charge.
In which type of bond are electrons?
Electrons are shared in a type of bond known as covalent. This type of bond is also considered a chemical bond.
What happens during a reduction/oxidation reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron
