What must a non-metal atom such as iodine do to become stable?
An atom of a nonmetal becomes an ion, specifically an anion, by attracting to itself one or more electrons from one or more atoms of one or more other and less electronegative elements.
The most basic unit of a substance?
Atom
Why won't stable elements react?
Stable elements do not react because they don't need to. Elements react so that they can gain stability( as stability is gained by filling the outer most shell of the atom). As stable elements already have full outer shells and are stable , they do not react.
Is NaF a metal or non metal?
Description belongs to the class of inorganic compounds known as alkali metal fluorides. These are inorganic compounds in which the largest halogen atom is fluorine, and the heaviest metal atom is an alkali metal. Kingdom Inorganic compounds
What is the basic properties of the group neon is on?
they are noble gases. except for Xe they do not react. Helium is the smallest atom.
Is nitrogen a metal atom?
No. It is a nonmetal.
Which two atoms forms a ionic bond?
An ionic bond forms between a metal atom and a nonmetal atom. The metal atom loses electrons to form a positively charged ion (cation), while the nonmetal atom gains those electrons to form a negatively charged ion (anion). The attraction between these oppositely charged ions leads to the formation of an ionic bond.
Do metal atoms decrease in size when they combines with nonmetal atom?
As metals have to become metal ions in order to chemically combined with nonmetals they have to lose their valance electrons. This process is associated with making the atoms smaller.
What happens to the outer electrons of a metal when it joins a non metal?
The outer electrons of a metal atom that bonds with a nonmetal atom are either transferred to the nonmetal to form an ionic bond or shared with the nonmetal to form one or more covalent bonds.
When a metal meets a nonmetal the nonmetal atom becomes what?
When a metal meets a nonmetal, the nonmetal atom tends to gain electrons to achieve a stable electron configuration, forming an anion (negatively charged ion) due to the addition of extra electrons. This creates an ionic bond between the metal cation and the nonmetal anion.
What kind of bond would a metal and a non metal typically make?
A metal and a nonmetal typically form an ionic bond. The metal atom donates electrons to the nonmetal atom, resulting in the formation of positively charged metal ions and negatively charged nonmetal ions that are held together by electrostatic attraction.
What happens to valence electrons as an ionic bond is formed between a metal and a nonmetal?
At least one, and usually all, of the valence electrons of the metal atom is donated to the valence shell of the nonmetal atom.
What charge does the atom have when a metal and a nonmetal meet?
it forms an ionic compound
What 2 atoms form an ionic bond?
Typically, a metal atom (such as sodium or potassium) forms an ionic bond with a nonmetal atom (such as chlorine or oxygen). The metal atom donates electrons to the nonmetal atom, resulting in the formation of ions with opposite charges that are attracted to each other.
How are replacement reactions similar to one another?
I think you mean displacement reactions. There are 2 types of displacement reactions: single, and double displacement. Single displacement is when a metal -nonmetal reacts with a metal or a nonmetal atom, and the metal or nonmetal atom switches places with the one in the molecule. Double displacement is when two molecules (same as above) react, and the metals/nonmetals (it doesn't really matter in this case) are swapped. They both have a switching of places between atoms, so I guess this is how they are similar.
What happens when an atom of metal an atom of nonmetal are combined?
The metal loses its electrons and trannsfers them to the non-metal to form an ioinic bond.
If you have a bond between a metal atom and nonmetal atom which of the two is more electronegative?
Generally the electronegativity is greater for nonmetals.
