A single atom of an element has 11 protons, 11 electrons, and 12 neutrons. Which element is it? Which atom has the smallest number of neutrons? What is the name given to an atom that gains or loses electrons in a chemical reaction?
What atomic particle in an atom is the same for each element? A single atom of an element has 11 protons, 11 electrons, and 12 neutrons. Which element is it? What element has 53 protons and 74 neutrons? If an atom with a mass number of 202 has 122 neutrons, it is an atom of whi...
Could another type of atom just happen to have 11 protons, 11 electrons and 12 neutrons ? No. The number of protons = the 'Atomic Number', which is sometimes referred to as 'Z', defines the type of atom, i.e. which element it is an atom of. As indicated in the List of Chemi...
Protons and Neutrons: What Are They?Jean Louis Van Belle
12 protons, 12 neutrons, 12 electrons. 12 protons, 12 neutrons, 10 electrons. 10 Reactivity Reactive in elemental form. Less reactive, stable in ionic form. 11 Occurrence In elemental Magnesium. In compounds and biological systems. 12 Role and Use Basic unit of element, used in manufacturing....
Electron has a minimal mass compared to protons and neutrons. The mass of an Electron is so small it's almost negligible. 6 Neutron Neutron can result in different isotopes of the same element. Carbon-14 has two more Neutrons than Carbon-12. 4 Electrons Electron orbits the nucleus in specif...
aThe element X has three isotopes: X-221, X-220, and X-218, with masses 220.9, 220.0, and 218.1 amu. The relative abundances of these three isotopes are 74.22%, 12.78%, and 13.00%, respectively. Calculate the atomic mass of element X. 元素x有三同位素: X-221, X-220和X-218,与大量...
Sodium is an alkali metal. It holds its place in the periodic table as the first element of the 3rd period. It is the eleventh element in the periodic table. Therefore,The atomic number of Sodium = 11,Number of neutrons in the nucleus of the Sodium ion...
