Answer:
they are in group II and they have two electrons in their outermost energy levels ( valency)...is this helpful?
Answer:
London dispersion forces
Explanation:
The London dispersion force is the weakest kind of intermolecular force. The London dispersion force is a temporary attractive force that occurs when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.
These London dispersion forces are mostly seen in the halogens (e.g., Cl2 and I2), the noble gases (e.g., Xe and Ar), and in many non-polar molecules, such as carbon dioxide and propane. London dispersion forces are part of the van der Waals forces, and are very weak intermolecular attractions.
Answer:
B. Cementation
Explanation:
The processes by which sediments are changed into rock are complex, but can be simplified into two processes, called compaction and cementation. Rounded sediment grains (ooliths) bound together with crystalline calcite.
Answer:
The attractive or repulsive interaction between any two charged objects is an electric force
Explanation:
that's the definition
A is the answer im pretty sure
