Covalent compounds are generally not very hard because they are formed by two or more nonmetallic atoms.
<h3>COVALENT COMPOUNDS:</h3>
Covalent compounds are compounds whose constituent elements are joined together by covalent bonds.
Covalent bonding occurs when two or more nonmetallic atoms of an element share valence electrons. This means that covalent compounds will not be physically hard since they constitute non-metals.
Examples of covalent compounds are:
- H2 - hydrogen
- H2O - water
- HCl - hydrogen chloride
- CH4 - methane

Answer:
thermometer
Explanation:
The most important tool to use when collecting data relating to how thermal energy affects metals would be <u>the thermometer.</u>
The thermometer is an instrument used to measure temperatures and the temperature of a body is a measure of the amount of thermal energy present in the body.
<em>In order to obtain data relating to how thermal energy affects metals, the most important variable to take note of would be the thermal energy of the metals and this can only be done by the thermometer.</em>
The answer is A, mass and volume.
The equation for density, <span>ρ,</span> is ρ = m/V. m is mass and V is volume.
From increasing atomic mass. He also made groups and periods.
