Electrons are both gained and lost in the formation of an ionic compound. The metal atom loses one or more electrons to the nonmetal with which it bonds. So the metal atom becomes a positively charged ion and the nonmetal atom becomes a negatively charged ion, and the ionic bond is formed by the electrostatic attraction between the oppositely charged ions, forming the ionic compound.

What is a reaction where free element element takes the place f an element in a compound?
A single displacement reaction is a type of chemical reaction where a free element replaces another element in a compound. This occurs when a more reactive element displaces a less reactive element in a compound, forming a new compound and releasing the displaced element.
Is sodium chloride a compound element homogeneous mixture or a heterogeneous mixture?
It is a pure compound, not a mixture at all.
Is zinc oxide a compound or an element?
Zinc is a chemical element. It is a transition metal, and zinc, which has the chemical symbol Zn, has an atomic number of 30. A link can be found below to check facts and learn more.Element
What are valence electrons and what do they determine?
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"
How do elements join to from compounds?
YES!!!! Taking Sodium and Chlorine as an example. Sodium metal is an element. Chlorine gas is an element. Put them together in a gas jar and they will react to form the compound sodium chloride. In nature atmospheric nitrogen (an element) will react with atmospheric oxygen (also an element), when a lightning strike discharges, to form nitrogen oxides (compounds).
What parts of an atom participate in chemical reactions?
Electrons are the parts of an atom that participate in chemical reactions. Specifically, it is the outermost electrons, known as valence electrons, that are involved in forming chemical bonds with other atoms.
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.
When forming a compound the chemical formula or compound is made stable with a net charge of zero by changing or adding?
When forming a compound the chemical formula or compound is made stable with a net charge of zero by the sharing of electrons (covalent compounds/molecules) or the transfer of electrons (ionic compounds).
What happens when an element combine?
In a proportional combination, a chemical reaction takes place forming a compound.
What type of reaction can an element and compound be combined?
An element and a compound can undergo a chemical reaction called a single replacement reaction. In this type of reaction, the element replaces one of the elements in the compound, forming a new compound and a different element as a product.
What best describes a single -replacement reaction?
A single-replacement reaction is a type of chemical reaction where an element replaces another element in a compound. This occurs when a more reactive element displaces a less reactive element from its compound, forming a new compound and releasing the displaced element.
Are valence electrons involved in chemical reactions?
Yes, valence electrons are involved in chemical reactions as they are the outermost electrons of an atom and are responsible for forming chemical bonds with other atoms. The number and arrangement of valence electrons determine the element's reactivity and ability to participate in reactions.
Will the element Barium become a negative ion?
No. Barium is a Group 2 element, and as such will lose its two valence electrons to form a Ba2+ ion when forming an ionic compound.
Is silicon dioxide an element or compound?
Silicon dioxide is a compound. It is composed of silicon and oxygen atoms in a 1:2 ratio, forming a chemical compound with the formula SiO2.
The valence electrons largely determine the chemical properties of an element and are usually the only electron used in?
The valence electrons are involved in forming chemical bonds between atoms. They determine an element's reactivity and ability to combine with other elements to form compounds. In general, only the outermost electrons, known as valence electrons, participate in chemical reactions.
What part of the atom is involved in a chemical bond?
A standard chemical reaction always and only involves a change in the electron configuration of the atom (either the number of electrons or their energy configuration).If the nucleus is affected (either the number of protons or electrons), then it is designated as a nuclear reaction, and this is quite different.
Is the electron affinity of an element positive or negative?
The electron affinity of an element can be either positive or negative, depending on whether the element tends to gain or lose electrons when forming chemical bonds.
