The bond order of a homonuclear diatomic molecule can be decreased by .?
You can decrease the bond order of a molecule like F2 or B2 by adding 1 electron to the neutral molecule.
What is energy released on adding an electron to an isolated gas phase atom?
All electron shells represent an energy level - it doesn't matter if its the outermost shell or not. In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron. The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.
This element has 15 protons and 15 electrons in its neutral atom?
Protons are particles with a positive charge, and in order for your atom to be neutral the positive charge must be cancelled out by adding negative charges of the same value. Electrons are negatively charged. So adding 15 electrons to 15 protons would result in a neutral atom. Also since your atom contains 15 protons it must be Phosphorus, element number 15.
How does the electron configuration of an ion of a group 1A or group 7A element compare to that of the nearest noble gas?
What relationship exists between the electron structure of Group IA ion and the electron structure of the nearest Noble Gas?
What happens to an atom's overall charge if it gains an electron?
since an electron is negatively charged, adding an electron to an atom will cause it to become negatively charged.
What is the meaning of a negative value for the electron affinity of an atom?
Electron affinity is the amount of energy required to remove an electron from an atom. Or an energy released by adding an electron to a gaseous atom ( ie, negative quantity). In this case, if an element has a negative Electron Affinity, its indicating that this element is stable than the neutral ones.
Why electron affinity of fluorine is large?
Electron affinity of an element is defined as the energy released by adding an electron to a gaseous atom of the element. With the electronic configuration of the fluroine atom being [Ne] 2s2 2p5, it needs just one more electron to form the fluoride ion (F-) which has the noble gas structure and is much more stable.

What is the charge of an atom that gains an electron?
since electrons are negative, you would subtract one from the original charge of the atom. For example, is the atom was neutral, the charge would then be 1-
Why does chlorine have more electron affinity than fluorine although it is below fluorine in periodic table?
Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.The reason that the electron affinity is not as high as might otherwise be predicted for fluorine, is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).
Which element has the distinguishing electron of 3s1?
The full electron configuration in question is 1s2 2s2 2p6 3s2 3p1. Adding up those electrons gives us a total of 13. Referencing a periodic table, we see that the atom with 13 electrons, and thus 13 protons to keep it neutral, is aluminum.
What is the electron configuration for fluorine ion?
[He] 2s2 3p5 is the electronic configuration of a neutral Fluorine atom. It's -1 ion (F-, fluoride ion), however is: [He] 2s2 3p6, or [Ne].

The of an atom are negatively charged?
Of course it it is. An electron is negative, while a proton is positive. Therefore, by adding an electron, its the same thing as adding a negative. 0 - 1 = -1. So to cut to the chase, adding an electron makes the atom negative.
What is made when a proton is added to an atom?
I believe a cation because adding a proton is like removing an electron, giving it a positive charge.Additional answerNot only that, but you'd also end up with a different element. The number of protons in the atom is specific to that element.
An atom can be changed into an ion by adding or removing?
an electron.
