You have to follow the Aufbau principle, which states that electrons populate the atomic orbitals situated at the lowest energy first.

The orbitals are:

333

4444

5555

666

Write the autoionization reaction for methanol, ch3oh.

aliina [53]

Autoionization Reactions are those reactions in which ions or molecules ionizes spontaneously without adding any external reagent.

For Example,
Autoionization of water.

H₂O + H₂O ⇆ H₃O⁺ + OH⁻

Autoionization reaction of Methanol is shown below,

In bullet points: explain the difference between thermal energy, heat and temperature.

sergeinik [125]

Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.

Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.

Copper atoms are used to produce pennies. The copper atoms in pennies share many electrons. Pennies contain

kaheart [24]

Answer:

Metallic bonds

Explanation:

Metallic bonds joins atoms of metals and atoms of alloys together. The copper used in making pennies is a metallic substance so it contains metallic bonds.

The formation of this bond type is predicated on the large atomic radius, low ionization energy and large number of electrons in the valence shell.
The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud.
The electron cloud is jointly formed by all the atoms by losing their outermost shell electrons.

This way the bond in pennies are metallic in nature.
