Chemical bonding is the joining of atoms to form new substances. The properties of these new substances are different from the properties of the original elements. An interaction that holds two atoms together is called a chemical bond. When chemical bonds form, electrons are shared, gained, or lost.
What else can I help you with?
What is key in determining whether an atom will form a bond with another atom?
Valence electrons
Which two atoms form an iconic bond?
Atoms that have lost one or more electrons form an ionic bond with an atom that has gained one of more electrons.
If calcium has 2 valence electrons and sulfur has 6 how many calcium atoms are needed to form a ionic bond with sulfur?
To form an ionic bond, calcium (which has 2 valence electrons) can donate its two electrons to sulfur (which requires 2 additional electrons to complete its valence shell). Therefore, one calcium atom can bond with one sulfur atom to form an ionic compound. Thus, only one calcium atom is needed to form an ionic bond with one sulfur atom.
What happens when two nitrogen atom share electrons?
They form a covalent bond.
What is formed When these outer electrons interact with other atom's electrons?
When outer electrons interact they form a bond. (ionic or chemical)
When an atom lose electrons in an ionic bond they form what?
they form cations
What kind of chemical bond will be formed between atom a and atom b if atom a loses electrons and atom b gains these electrons?
An ionic bond will form between atom a and atom b if atom a loses electrons and atom b gains these electrons. Atom a becomes a positively charged ion (cation) and atom b becomes a negatively charged ion (anion), resulting in an electrostatic attraction between the two oppositely charged ions.
As a bond between a hydrogen atom and a sulfur atom is formed electrons are?
The pair of electrons is shared to form a covalent bond.
What is key in determining whether an atom will form a bond with another atom?
Valence electrons
When an atom completely gives up its valence electrons to another atom they form a bond that is considered to be?
ionic
How are electrons used in atoms?
They allow the atom to form a bond with another atom(s) either covalently or ionicly. This can be achieved by sharing (covalent bond) or giving/loosing (ionic bond) electrons.
When a pair of electrons is shared between two atom what form is the bond called?
covalent bond
What are donated or shared when two atoms form a bond?
When two atoms form a bond, electrons are donated or shared. In an ionic bond, one atom donates electrons to the other, while in a covalent bond, electrons are shared between the atoms.
Which two atoms form an iconic bond?
Atoms that have lost one or more electrons form an ionic bond with an atom that has gained one of more electrons.
If calcium has 2 valence electrons and sulfur has 6 how many calcium atoms are needed to form a ionic bond with sulfur?
To form an ionic bond, calcium (which has 2 valence electrons) can donate its two electrons to sulfur (which requires 2 additional electrons to complete its valence shell). Therefore, one calcium atom can bond with one sulfur atom to form an ionic compound. Thus, only one calcium atom is needed to form an ionic bond with one sulfur atom.
Which part of atoms will form an ionic bond?
Atoms will form an ionic bond when one atom donates an electron to another atom. Typically, this occurs between a metal atom (which tends to lose electrons to form positive ions) and a non-metal atom (which tends to gain electrons to form negative ions).
Which bond forms by sharing electrons in the outermost shell?
The sharing of electrons between atoms forms a covalent bond. If electrons are donated from one atom to another to form a bond this would be an ionic bond.
