Question: Describe how changing the number of protons in the nucleus changes the atomic number.

In this blog post, we will explore how changing the number of protons in the nucleus changes the atomic number of an element. The atomic number is a fundamental property of an element that defines its identity and position in the periodic table. The atomic number is equal to the number of protons in the nucleus of an atom. Protons are positively charged particles that make up part of the nucleus, along with neutrons, which have no charge. The number of protons determines the electric charge of the nucleus, which affects how the atom interacts with other atoms and molecules.

If we change the number of protons in the nucleus, we are essentially changing the element into a different one. For example, if we take a hydrogen atom, which has one proton and one electron, and add another proton to its nucleus, we get a helium atom, which has two protons and two electrons. The atomic number of hydrogen is 1, while the atomic number of helium is 2. By adding a proton, we have increased the atomic number by 1 and changed the element from hydrogen to helium.

Similarly, if we remove a proton from the nucleus, we decrease the atomic number by 1 and change the element into a different one. For example, if we take a carbon atom, which has six protons and six electrons, and remove one proton from its nucleus, we get a boron atom, which has five protons and five electrons. The atomic number of carbon is 6, while the atomic number of boron is 5. By removing a proton, we have decreased the atomic number by 1 and changed the element from carbon to boron.

Changing the number of protons in the nucleus is not an easy task, as it requires a lot of energy and special conditions. Usually, this happens in nuclear reactions, such as fission, fusion or radioactive decay, where atoms split or combine or emit particles and energy. In these reactions, some protons are converted into neutrons or vice versa, resulting in different elements with different atomic numbers.
