can someone explain the following and give examples: protons nuetrons and electrons there charges etc.(for 30 points)​
alexdok [17]

Explanation:

Protons are positively charged sub-atomic particles that are in the nucleus of an atom and have a relative mass of 1. Neutrons have a neutral charge, meaning they have no charge, and are also in the nucleus of an atom with a relative mass of 1.Electrons are negatively charged particles that orbit the nucleus in electron clouds. They are said to have a relative mass of 0.

For example, a sodium atom is number 11 on the periodic table. The atomic number of sodium tells us the no. of protons contained within its nucleus as well as the number of electrons orbiting. So we can say that sodiun has 11 electrons and 11 protons. To determine the number of neutrons, simply subtract the number of protons from the mass number( found on periodic table)

23-11=12 neutrons

Which adaptation would be most helpful to animals in a desert?
dybincka [34]

Explanation:

Therefore, most adaptations in desert animals, while they may seem bizarre, serve the purpose of helping that animal cope with these two problems. Both are important. Water is necessary for life, and balancing the water budget is essential for desert animals.
