Give the charge of the most probable ion from the element Be?
The most probable ion of beryllium is Be^2+ because it loses its two valence electrons to achieve a stable electron configuration.
Why these iodine form an ion with a charge of -1?
iodine has 7 electrons in the valence shell. and needs one more electron to attain stable noble gas configuration. So it gains one electron and forms iodide ion with charge of -1.
How many valence electrons does chlorine have?
Chlorine has seven valence electrons. The electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p5. These seven valance electrons do NOT readily react, because they are 'tightly' held to the nucleus. However, chlorine has strong electron affinity; Electronegativity; this means it will attract one electron into its valance shell , to complete the octet of eight electrons in the valance shell. When this 'extra' electron combines into to valance shell , the electron configuration is 1s2, 2s2, 2p6, 3s2, 3p6. , and the chlorine atom is now a 'CHLORIDE ANION' of charge '-1' , (symbolised by Cl^(-)).
What is the effective nuclear charge experienced by calcium's valence electrons?
as you know we must first have the electron configuration to get the valence electrons. the electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2. we now have the electron configuration but we dont have the v.e. the last electron in the calcium atom are in the 4s orbital so that means that since it the only electron in the 4s orbital we will use it as a v.e. so as to get the v.e. we will subtract the shielding electrons from the nuclear charge shortly expressed by the formula below. Zeff=S-Z in this case Z will be the sum of the shielding electrons and s is the nuclear charge. Zeff=20-18 Zeff=2+ so the effective nuclear charge is 2+ or 2. hope you like it.
What ions does not have a noble gas electron configuration S-2 Sr 2 I- Cs or Be 3?
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
What is the most likely charge on an ion formed by an element with a valence electron configuration of ns 1?
The most likely charge on an ion formed by an element with a valence electron configuration of ns1 is +1. This is because elements with ns1 configuration tend to lose one electron to achieve a stable noble gas configuration, which results in a +1 charge.
What is the valence of potassium?
Potassium has a valence of +1. This means that it typically forms ions with a positive charge of +1 by losing one electron to achieve a stable electron configuration.
Why does Li have a 0 charge?
Lithium does not have a '0' charge. Its electron configuration is 2,1. This means there is one valence electron in its outer shell. Losing this electron will make Lithium have a full shell (2 only) which all atoms try to achieve, therefore Li has a +1 charge because it loses an electron to gain noble gas configuration.
If atoms of a halogen non metal gain one electron the atoms then have how many valence electrons?
This atom become an anion with negative charge -1.
What is the valence of a monoatomic chlorine ion?
The valence of a monoatomic chlorine ion is 1 and its charge is -1.
Give the charge of the most probable ion from the element Be?
The most probable ion of beryllium is Be^2+ because it loses its two valence electrons to achieve a stable electron configuration.
When an element loses an electron what happens to the charge of the element?
When "x" valence electrons are lost the charge is +x When "x" valence electrons are gained the charge is -x for example, if chlorine gained one electron, the charge would be Cl 1- or, if magnesium lost two electrons, the charge would be Mg 2+
What charge does a nitride ion have?
Nitride ion has a charge of -3. This is because nitrogen, the element that forms the nitride ion, has 5 valence electrons and gains 3 electrons to achieve a stable electron configuration, resulting in a total of 8 electrons and a charge of -3.
Why these iodine form an ion with a charge of -1?
iodine has 7 electrons in the valence shell. and needs one more electron to attain stable noble gas configuration. So it gains one electron and forms iodide ion with charge of -1.
What element has a full valence shell with electrons?
Helium. (A hydride ion has the same electronic configuration, but hydride is not an element since it has a net electric charge.)
What element forms an ion with an electronic configuration of Ar with a -2 charge?
The element that forms an ion with an electronic configuration of Ar with a -2 charge is oxygen (O). When oxygen gains two electrons, it achieves a stable electron configuration similar to argon.
What is the ion charge of boron?
The most common ion charge of boron is +3. Boron is typically found in compounds with a valence of +3 due to its electron configuration.
