When two or more elements form a bond, they do so either by sharing electrons, or by one element donating and one element accepting electrons. In the former case, you have a covalent bond. In the latter case, it is an ionic bond.

What substance that contains 2 or more elements chemically combined in a fixed proportion?
A substance made of two or more elements chemically combined in a specific proportion is called a compound. A substance composed of two or more elements combined chemically in a fixed proportion by mass is called a compound. A chemical compound can be held together by a covalent bond or an ionic bond.
What are the chemical properties of group 8 elements?
They don't have one. Group 8 is noble gasses.
What compound do the sodium and sulfur ion make?
The sodium and sulfur elements make the compound of sodium sulfide or Na(2)S. *(2)=subscript 2 The reason for this is because this is an example of an ionic bond (or a bond between a metal and a non-metal) in this case the Sodium is a metal and the sulfur is a non-metal. Since sodium has a charge of +1 and sulfur has a charge of -2 there has to be 2 sodium and one sulfur, thus making the charges of the two elements cancel out.
What will form an ionic bond with nitrogen?
All group 1 metals and group 2 elements excluding beryllium will form ionic compounds with nitrogen.
Does sodium and nitrogen form a covalent or ionic bond?
In an ionic bond, one of the elements is a metal, the other a non metal. Sodium is underneath the classification of "alkali metals", whilst Nitrogen is a non metal. Therefore, the bond between these two elements is ionic. The formula would be Na3N. Thanks. Very helpful.
What happens when a single covalent bond forms between 2 elements?
Each atom contribute with one electron to the bond.
What happens when 2 or more atoms bond by sharing electrons?
h
What happens to compounds when they break down?
They become 2 or more elements
How do you get a compound?
To make a compound, bond 2 or more different elements chemically. An example would be to bond iron and sulphur to make iron sulphide.
Which term best difines two or more atoms joined by a chemical bond?
The term molecule or compound best defines two or more atoms joined by a chemical bond.
If 2 or more elements are joined together they form a?
compound or solution. he could be talking about a covalent or ionic bond
What term describes a substance that is made when two or more different atoms bond together in a certain ratio?
When 2 or more elements make a chemical bond giving a new material that material wi be a compound,
What is a rule for predicting whether or not a bond will be ionic?
If the difference in electronegativity between the elements is greater than 2 then the bond will be ionic, if its between 1.6 and 2 then it will be ionic if one of the elements is a metal.
What elements are most likely to form an ionic compound?
Members of groups 1, 2, 6, 7 in the Periodic Table are most likely to form ionic compounds. It depends on what pair of elements are involved, for instance one rule of thumb is metal with nonmetal. Another, more systematic way, to assess this is to consider the difference in electronegativity between the two elements. If the electronegativity difference is 2 or more then the bond will be ionic. If the difference is less than 2 but more than 1.6 and one of the elements is a metal then there can be an ionic bond.
What determines the stability in a covalent bond?
similarity of electronegativity of the 2 elements
What element is a polar covalent bond?
No single element can form a bond. Only 2 or more elements can form bonds. Polar bonds occur when there is a dipole moment, or there is asymmetry in the structure. For example, HF forms a polar covalent bond.
In group 2 on the periodic table are they positive ions when they bond with other elements?
Elements from the group 2 of the periodic table form cations.
