An atom has an atomic number of 12 and a mass number of 25. how many neutrons does the atom have? If an atom with a mass number of 202 has 122 neutrons, it is an atom of which element? What is the atomic number of an atom that has 6 protons, 6 ...
What neutral atom has the same number of electrons as Sc3+? Isoelectronic Species Isoelectronic species are those that have equal electrons. These can be atoms, molecules or ions. They have different physical properties and different chemical properties. Answer and Explanation: Scandium ...
- The third shell has 7 electrons. - Therefore, the total number of electrons is calculated as: 2+8+7=17 electrons 3. Determine Atomic Number: - For a neutral atom, the number of electrons is equal to the number of protons. - Thus, the atomic number, which is the number of prot...
N(7), F(9), P(15), Ar(18) View Solution An element has electronic configuration 2, 8, 3. What is the atomic number of the element ? To which (i) group and (ii) period does this element belong ? View Solution An element has 2 electrons in the M shell. What is the atomic nu...
What changes when an ion is made from an atom?A:the number of electrons onlyB:the number of neutrons onlyC:the number of protons onlyD:the number both of protons and of neutrons 相关知识点: 试题来源: 解析 A 考查实际运用。A. 仅电子数量(变化),B. 仅中子数量(变化),C. 仅质子数量(变化...
Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative charges on all the electrons. But sometimes an atom can gain or lose an electron to become what's called an ion. If it ...
An atom is the smallest unit by which matter is made up of. The atom has electrons, protons and neutrons as the constituent particles and is electrically neutral. We study atom and its properties in chemistry.Answer and Explanation: The 2s orbitals can have a maximum of two electrons....
Since each shell has a definite number of orbitals and each orbital occupies an electron pair, each shell has a maximum electron count (maximum occupancy). Electrons in an atom are identified using quantum numbers. Answer and Explanation: The allowed values of l, ml ...
