Answer: Option (d) is the correct answer.

Explanation:

A property that does not bring any changes in the chemical composition of a substance is known as a physical property.

For example, hardness, density, boiling point, conductive nature etc are all physical properties.

On the other hand, a property that brings changes in the chemical composition of a substance is known as a chemical property.

For example, reactivity, toxicity etc are all chemical properties.

Thus, we can conclude that ability to combine with hydrogen is not a physical property.

What a substance reacts with is not a physical property, but rather a chemical one. The answer is "ability to combine with hydrogen"

nevsk [136]

To determine if the compound is an ionic compound, heat it up until the compound reaches its melting point and become molten. Use the molten form to set up an electric circuit and see if the compound will conduct electricity. If the compound conduct electricity then it is an ionic compound. If it does not conduct electricity, it is not an ionic compound. Ionic compounds usually conduct electricity in their molten forms.

Molecules with ____________ bonds between their components will ____________ (fall apart) in water, releasing charged particles

Musya8 [376]

Molecules with ionic bonds between their components will dissociate (fall apart) in water, releasing charged particles called ions.
When the number of protons and electrons are not equal, ion is formed. There are two types of ions, Cations and anions. Cations are the positively charged ions and when an atom gains electron, Cation is formed. Anions are negatively charged ions and when an atom loses electrons, anion is formed.

Describe the orbital notation and electron configuration notation to describe the placement of all of the electrons in an atom o

andriy [413]

The arrangement of the electrons on the orbitals is governed by the principles of quantum energy. To be able to draw the correct electronic configuration of an element, they should follow these three principles.

1. Aufbau's Principle. The electrons of an element should be filled up from the highest energy level. You can use the periodic table as a guide for this. In decreasing order, the energy of the orbitals are 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d and 7p. Each 'box' of these orbital must be filled with two electrons from 1s before moving on to the next.

2. Hund's rule. This states that you must fill all boxes of one orbital with one electron first. For example, 2p has 3 boxes. You fill one electron for each box first before going back to fill it to two electrons if there are still excess.

3. Pauli's Exclusion Principle. This states that no electrons of the same element should have the same quantum numbers. To achieve this, the two electrons in each box should have opposite spins, one facing up, and the other facing down.

Using these three rules, you will be able to draw the electronic configuration of Fluorine with 9 electrons as shown in the picture.
