The brackets are indicating a(n) bond. A bond between two molecules. Each molecule consists of two small atoms connected to a bigger one. This bond is formed between one small atom from one molecule and the big atom from the other molecule. This small atom has a delta plus charge, and the big atom has a delta minus charge. This bond is marked by three points. hydrophobic hydrogen ionic polar covalent single (nonpolar) covalent

Which of the following is an indication that a substance has undergone a chemical change? a. no new product has been formed. b. the color of the substance has not changed. c. the original constitute has not changed. d. the molecular structure has changed.

One nanometer is equal to how many meters?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
