Whether an ISOTOPE (not element) is naturally radioactive depends not only on the number of protons, but also on the number of neutrons. For EVERY element, there are radioactive isotopes.There has to be a certain relationship between the number of protons and the number of neutrons, but the relationship isn't a simple one.
It should isolated from underground water and isolated from rivers and drinking water. It should be away from expected earthquake
A clef is needed for any pitched voice or instrument.

In the context of crash dynamics, the phrase "is not described" suggests a lack of information or explanation regarding a particular aspect within the crash dynamics section. This could indicate a gap in the coverage of the topic or an omission in the discussion of crash dynamics principles. Further clarification or additional details would be needed to pinpoint the specific element that is not described within the dynamics of a crash.
they needed wood and eventually they had to trade their surplus for it and other things they didn't have but needed badly.
The number of protons defines an element - the number of neutrons isn't needed to find the identity of the element. All ions and isotopes with 44 protons is ruthenium. However, with the information about the neutrons, we know the specific isotope: 101Ru.
The number of protons defines the element. If an atom has six atoms, then it can only be carbon. If it has six neutrons, then it is 12C.
An element is defined a "type of atom"; to be more precise, all the atoms in an element have the same number of protons (but not necessarily the same number of neutrons).
In a Nuclear reaction, an atom of one element changes into another element or into an isotope of the first one, depending on what sort of radioactive decay it undergoes. The Nucleus of every atom contains Neutrons and Protons. All the Protons being positively charged repel each other. Hence a large Nuclear Force called Binding Force acts on all the protons and keeps them forced into the Nucleus. When the number of protons in the nucleus decreases due to a Nuclear reaction, the amount of force needed to hold all the protons in the Nucleus decreases. The remaining force is given out as heat energy.
An element with 11 protons will have atomic number 11, or sodium. If the element has 11 neutrons, then it has an atomic mass of 11+11 = 22. Therefore, the isotope Sodium-22 has 11 protons, neutrons, and electrons.
The number 17 in 35Cl represents the atomic mass of chlorine, which is the sum of protons and neutrons in the nucleus. Since the atomic number (number of protons) is sufficient to uniquely identify an element, the number 17 is not needed to describe chlorine.
It has 8 protons. The atomic number of an atom = the number of protons. The mass number is not needed in this problem. The mass number is the number of protons + number of neutrons.
In an Oxygen atom's nucleus, there are 8 protons. In a neutral atom, there are also 8 electrons. Oxygen also has an atomic (protonic) number of 8, meaning that it has 8 protons. On the periodic table, elements are listed according to increasing atomic numbers.
You still need to know the number of protons present in order to find the atomic mass.
Firstly, I assume that this question mentions about the element in the periodic table which has the atomic number of 115. Let us discuss about the atomic structure at first. Basically, this type of atoms must have 115 protons, 115 electrons. According to the tendency of the increase in the number of neutrons in the nucleus, with the atomic number, this element should contain at least 150 neutrons. Additionally, as the atomic number of this element exceeds 84, it must be radioactive and unstable in the nature. Hence, it would not occur naturally even as compounds. So when needed it has to be synthesised using lighter atoms with nuclear fissions.
Atoms are made of different numbers of protons, neutrons, and electrons. Protons (positive charge) and Neutrons (neutral charge) make up the nucleus of the atom. The incredibly small electrons (negative charge) follow orbitals around the nucleus in what's known as an Electron Cloud. An example where this is not true, however, is a hydrogen atom. It has only one proton and one electron. Because it only has one proton, it does not naturally have any neutrons as no buffer is needed between protons.
The element is vanadium (V) because it has 23 protons. With 18 electrons and a net charge of 3 plus, it would have lost 3 electrons, resulting in a net charge of +3. The number of neutrons (28) does not affect the charge or identity of the element.
