What is noble gas notation? Electron Configuration: The current model of the atom is the quantum mechanical model. In this model, each element has a unique electron configuration. Noble gases are the family of elements that are nonreactive because their valence electrons are full. ...
For instance, the outer shell of Helium has 2 valence electronswhile the outer shell of Xenon has 8 electrons. Nowadays, there remains to be afew noble gases because of the low chemical reactivity of these said gases. F. 5.because of their properties, noble gases have many important...
Write the noble-gas notation for the electron configuration of Se What is a valence electron? An atom's electron configuration ends with 3p4. If another atom has seven more electrons, what would be the continuation of the electron configuration? a. 3p63d34s2 b. 3p43d54s2 c. 3p64s23d3...
Atoms are the fundamental unit of an element. They consist of a nucleus and surroundingelectrons. When an atom has an incomplete electron shell, it is said to have valence electrons. When two or more atoms come together to share outer shell valence electrons, a chemical (covalent) bond is f...
What Is a Noble Gas Configuration? How to Know If an Element Has a Positive or Negative... How Many Valence Electrons Does Sodium Have? What is a Polyatomic Ion? What is an Ionic Compound? Why Is Carbon So Important to Organic Compounds? What is a Monatomic Ion? What Determin...
For instance, the outer shell of Helium has 2 valence electrons while the outer shell of Xenon has 8 electrons. Nowadays, there remains to be a few noble gases because of the inherent low chemical reactivity of these said gases. 5. Because of their properties, noble gases have many ...
A valence electron is an electron that 'lives' in the last electron shell (or valence shell) of an atom. The atom will have one or more electron shells based on how many electrons the atom has. The very last shell that the atom has holds the valence electrons. The number of valence ...
1.Whattype of elements give off valence electrons to achieve a configuration of a noble gas? Metals give off valence electrons. Metals form cations 2.How is a covalent bond formed? Covalent bonds are formed when electrons are shared to complete an octet. 3.Write the Lewis structure for NH3...
It doesn’t describe neither how many valence electrons they have, nor how many electrons they additional needs or have to loos to reach their noble gas state. The question simply asks how many electrons the corresponding nobel gas state for each atom has to contain. ...
(ii) What is the number of valence electrons in its atom? (iii) What is its valency? (iv) What is the name of the element? (v) What will be the formula of the compound formed by Y with sodium? View Solution One mole of an ideal monoatomic gas is taken at a temperature of...
