Boron, Krypton,Neon, and Radon Krypton, Neon and Radon do not gain electrons. Because an atom wants to have eight electrons in their valence shell or their outermost shell, and Krypto, Neon and Radon are Noble Gases which already have eight in their valence shells, so they don't lose or gain electrons. And as for Boron it want's to gain 5 electrons because it only has three in its valence shell.
What else can I help you with?
Do atoms of the halogen family of elements typically gain two electrons when they react?
Yes, halogen atoms typically gain one electron to achieve a stable electron configuration. This results in a full outer electron shell, similar to the noble gases.
How many valence electrons does gold have?
The number of electrons in a neutral atom of any element is the same as the number of protons in the nucleus of the atom. The number of protons in an element is the same as the atomic number for that element. In the case of Gold (Au) the atomic number is 79.
What element has 1 electrons?
Technically, ANY atom could have "one electrons" or, as I suspect you mean to ask, one electron. In its uncharged state, a protium atom, also known as a hydrogen-1 atom, is the only atom posessing a single electron, but in theory any atom could have any number of its electrons stripped off, and be left with only one (or even none).
What subatomic particles makes an element reactive?
Electrons are the subatomic particles that make an element reactive. Elements react with one another by gaining, losing, or sharing electrons to attain a more stable electron configuration.
Atoms that have or electrons in their valence shells tend to gain electrons to form charged ions?
an ion.
Does bromine lend or borrow how many electrons?
Bromine tends to gain one electron to achieve a stable electron configuration, making it an electron acceptor (accepts one electron).
What atom tends to gain one electron when it combines with another atom?
All elements in the 7th family/group (2nd from the right) on the Periodic Table.
Does fluorine gain or loose electrons?
Fluorine gains electrons to achieve a stable electron configuration. It has seven valence electrons and tends to gain one more electron to complete its outer shell and attain a full octet.
How many electrons does iodine lose or gains when it forms a ion?
Iodine tends to gain one electron when it forms an ion.
Does bromine tend to lose or gain electrons to become an ion?
Bromine tends to gain one electron to become a Br- ion.
What are the oxidation number of calcium and chloride?
The oxidation number of calcium is +2, as it tends to lose two electrons to achieve a stable electron configuration. The oxidation number of chloride is -1, as it tends to gain one electron to achieve a stable electron configuration.
Which group of elements on the periodic table tends to form ions?
Group one, not including element 1 (helium) tend to form ions.
Will lithium gain one electron when it reacts to form a compound?
No, lithium loses one electron to form a compound. It is an alkali metal with an electron configuration of 1s² 2s¹, so it tends to lose one electron to achieve a stable electron configuration.
How many outer rings electrons does sodium and chlorine have?
Sodium has one outer ring electron, and chlorine has seven outer ring electrons. Sodium tends to lose its outer electron, while chlorine tends to gain an extra electron to achieve a stable electron configuration.
What is the valence number of bromide?
in the valence shell of bromide 7 electrons are present. So the valency of bromide is 1
How many electrons does iodine lend?
Iodine tends to gain one electron when forming ionic compounds. This means that iodine typically lends one electron to achieve a stable electronic configuration.
What is the oxidation number of fluoride?
The oxidation number of fluoride is -1. Fluorine is a group 17 element and tends to gain one electron to achieve a full outer shell, giving it a -1 oxidation state in most compounds.
