Question 14 Select the following that can be considered an electron group. [Select all that apply] O Single bond O Triple bond O Double bond O Lone pair of electrons

State the three parts of Dalton's atomic theory. (Select all that apply.) No atoms are gained, lost, or changed in identity during a chemical reaction. Atoms tend to gain, lose, or share electrons to achieve an octet of electrons in their outer shell. Chemical combination is the bonding of a definite number of atoms of each of the combining elements to make one molecule of the formed compound. The electronegativity difference between two atoms determines the type of bond that will form. Each element is composed of small indivisible particles called atoms, which are identical for that element but different from atoms of other elements. Bonds are formed by the sharing or transfer of electrons. When a compound burns, it is reacting with oxygen in the air.
