To solve the question, we need to determine the atomic number and mass number of the ion X2− which contains 10 electrons and 8 neutrons. We will also identify the element represented by X. Step 1: Determine the number of protonsThe ion X2− has a charge of -2, which means it ...
The atoms contain 8 protons and 10 neutrons. Express your answer as an isotope. What is the name of the element that has an atomic number of 8? Which atom has the smallest number of neutrons? What is an atom that has more protons than electrons?
What element has 13 electrons? What element has 10 electrons? What is the chemical element radon? What is the fourth element on the periodic table? What chemical element is U? What is the symbol for the element lead? Which element has an atomic number of 8?
1-Electron configuration for Cl^{-} 2- What is the atomic symbol for the noble gas that also has this electron configuration? An ion from a given element has 11 protons and 10 electrons. What is the charge on the ion? What ...
No of electons in M^(2+) ion =10 Atomic numbr of element M= 10 + 2 = 12 No of protons in element M=12 Mass number of element M = No of protons + No of neutrons =12+12=24 The element M with atomic numbr 12 is magnesium (Mg)
In an element, the numbers of electrons and protons are equal. Moreover, since they have opposite charges, they cancel each other out and keep the atom neutral. The total number of protons present in the atom of a substance is known as theatomicnumber. Atomic mass refers to a weighted ...
the spin of an electron never changes, and it has only two possible orientations. In addition, the very notion that electrons and protons are solid 'objects' that can 'rotate' in space is itself difficult to sustain, given what we know about the rules of quantum mechanics. The term 'spin...
Toothpaste, which comes in many different varieties, is one of the most commonly used household items. It is used to maintain oral hygiene, and an important element is added to toothpaste to help with that. Answer and Explanation: Learn more about this topic: ...
Protons, with their greater mass, contribute significantly to the atomic mass of an element, alongside neutrons, which have a similar mass but no charge. 8 Electrons determine the atom's chemical behavior and its ability to form bonds with other atoms. This is because electrons can be shared ...
The arrangement and number of electrons largely determine an atom's chemical behavior. 6 What happens if an atom has more electrons than protons? It becomes a negatively charged ion, called an anion. 6 Why are protons crucial to an element's identity? Because the number of protons determines...
