3. Describe nuclear fission. What happens to the atomic number, mass number, protons, neutrons? Be able to write the reaction eq
MaRussiya [10]

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a large amount of energy. In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process. The case of decay process is called spontaneous fission and it is very rare process. In this section, the neutron-induced nuclear fission, the process of the greatest practical importance in reactor physics, will be discussed.

Fusion reactions between light elements, like fission reactions that split heavy elements, release energy because of a key feature of nuclear matter called the binding energy, which can be released through fusion or fission. The binding energy of the nucleus is a measure of the efficiency with which its constituent nucleons are bound together. Take, for example, an element with Z protons and N neutrons in its nucleus. The element’s atomic weight A is Z + N, and its atomic number is Z. The binding energy B is the energy associated with the mass difference between the Z protons and N neutrons considered separately and the nucleons bound together (Z + N) in a nucleus of mass M. The formula is

B = (Zmp + Nmn − M)c2.

Why is the right side
vladimir1956 [14]

Answer:

The elements on the left-side of the periodic table are relatively electron deficient. So due to their comparatively low effective nuclear charges (the net positive charge of the protons minus the shielding core electrons below the valence level), their electrostatic hold on these electrons are weak.

Elements further right on the period table though,  have higher effective nuclear charges and stabilize electrons more effectively. Which leads to localized covalent bonding and the formation of molecules.

The right side contains non metals while the left side contains metals.

Metals lose electrons (negative electrons). They now have more protons,  therefore making the ion positive.

Non metals gain electrons (positive electrons). So the ion has more electrons than protons which makes the ion negative.

Which of the following is used to measure weight?
Alika [10]
The answer would be kilograms. Otherwise Liters measure volume, Newton's measure force and Meters measure distance.

In terms of temperature, pressure and volume, what is happening when a hot air balloon inflates?
oksano4ka [1.4K]

Explanation:

This means that when the gas in a hot air balloon is heated, the gas expands. The balloon has a fixed volume, but there is a hole at the bottom. So, the extra volume flows out of the hole in the bottom of the balloon. Since there is less air in the same volume, its density decreases
