What happens in a reduction?
An element gains one or more electrons
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?
The same number of valence electrons as xenon.
Can oxygen accept and donate electrons?
Under normal conditions of temperature and pressure, oxygen gains electrons. The outermost orbital in an oxygen atom has four electrons., i.e., the outermost orbit has six electrons. Hence, to reach the octet configuration, oxygen can take two more electrons. Thus, oxygen is electronegative.
An element with 20 protons and 20 electrons gains one electron The electron goes into what type of orbital?
3d
How many electrons does the element Be have in it?
4 electrons, 2 valence electrons
When this element gains 2 electrons it has the electron configuration of the noble gas Argon?
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
An element that gains electrons when combining with other elements is a?
A metalloid :)
What happens in a reduction?
An element gains one or more electrons
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
What happens when an element gains electrons?
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained. The process in which an atom gains electrons is known as reduction.
What charge is present on an atom when it gains 2 electrons?
When an atom loses two electrons it becomes +2, as Mg, Ca, Ba.
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?
The same number of valence electrons as xenon.
How many electrons does nitrogen lose?
Nitrogen is a NON-metallic gas. It does not IONISE readily. However, it has ELECTRON AFFINITY. This means that it will gain electrons to form a negative ion (ANion) When an atom of nitrogen gains electrons it is shown as 'N^(3-).
The number of electrons in the outermost shell of an element is 5 what is its valency and why?
Its valency is 3 i.e. 8-5.The element is a non metal since it has 5 electrons in the outermost shell.Hence, it is very difficult for the element to loose 5 electrons and would be easier togain 3 electrons .Hence, the element gains 3 electrons and thus we consider its valencyto be 8- no. of valence electrons.
Does bromine lose or gain electrons?
it gains electrons.
How many electron does barium have to give up to achieve a noble gas electron configuration?
Two electrons
What is the difference between an atom an isotope and an ion?
an ion is when an element loses or gains one or more electrons. an isotope is when a element loses or gains one or more neutrons. when one or more proton(s) is/are gained or lost, it becomes a different element.
