Which is a characteristic of all ions?

They are metals.
They have a charge.
They are made of two or more types of atoms.
They form chemical bonds through electron sharing.

Answers

Answer 1

Answer:

D. They form chemical bonds through electron sharing.

Explanation:

Answer 2

The correct characteristic of all ions is that they have a charge. Therefore option B is correct.

An ion is an atom or a molecule that has gained or lost electrons, resulting in an unequal number of protons and electrons. This imbalance of positive and negative charges gives the ion a net electrical charge.

Ions can have a positive charge (called cations) if they have lost electrons, or a negative charge (called anions) if they have gained electrons.

The charge of an ion is essential in determining its behavior and interactions with other ions and molecules. It influences the way ions form chemical bonds and participates in chemical reactions.

The charge of an ion is indicated by a superscript after the chemical symbol, such as Na+ for a sodium cation or Cl- for a chloride anion.

As temperature changes, rocks expand and
contract. The rocks eventually break into
smaller pieces. Which process accounts for
this expansion and contraction of rocks?

Answers

Answer:

Thermal heating and cooling

Explanation:

This process described results from thermal heating and cooling as a mechanism of mechanical weathering of rock bodies.

It is often more pronounced in the arid regions of the world where there is a significant difference between day and night temperatures. With mechanical weathering, rocks are broken down into fragments by physical disintegration. During the day, the high temperature causes the rock to expand significantly. At night, the rock contracts and on the long run, joints and fractures begins to appear on the rock surface.

What happens when two magnets rappel each other hehe

Answers

Answer:

Every magnet has two sides: a north pole and a south pole. We use these names because if you hang a magnet from a thread, the magnet’s north pole points (almost) towards the north direction.

This is because the Earth’s core (its centre) is a large, weak magnet. Your little, strong magnet lines up with Earth’s magnetic core, so it points north. That’s how a magnetic compass works.

How do you determine if a polyatomic ion needs to be counted together?

Answers

Answer:

Calculate from Oxidation Number

The oxidation number of oxygen is -2, and the oxidation number of hydrogen is +1. Add together the oxidation numbers of all the atoms in the polyatomic ion. In the example, -2 +1 = -1. This is the charge on the polyatomic ion.
