How do the atoms of a molecule stay together? Molecules: Molecules form when two or more atoms join together chemically to create a new substance. In some cases, the two or more atoms will be of the same element. Other times, the atoms will be from two or more different elements to fo...
Lewis Electron dot Structure By Gilbert Lewis Consist of a chemical symbol of an element surrounded by a number of dots. The chemical symbol represents the nucleus of the atom. The dots represents the valence electrons Ex: 1A 2A 3A 4A 5A H... Li.. Be.. B.. C.. N... Types of bon...
Atoms cannot be created or destroyed. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms. Atoms of same element can combine in more than one ratio to form two or more compounds. How do atoms behave? Electrons are attracted...

answer. gram atomic mass refers to an element’s atomic mass expressed in grams. one gram of any element contains 6.022 × 10 23 of the element’s atoms. it is the same as one mole of atoms. one gram of atomic mass equals 6.022 × 10 23 atoms = one mole. q12. a) state the ...

An atom is the smallest possible amount of a chemical element—so an atom of gold is the smallest amount of gold you can possibly have. By small, I really do mean absolutely, nanoscopically tiny: a single atom is hundreds of thousands of times thinner than a human hair, so you have ...
All atoms of an element have identical chemical properties and mass whereas, atoms of different elements have different chemical properties and masses. Atoms combine in a ratio of small whole numbers to form compounds. The matter is anything and everything in our surrounding. It has basic structur...
Atoms of each element contain a characteristic number of protons and electrons. The number of protons determines an element’s atomic number and is used to distinguish one element from another. The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom...
