Why does fluorine atom atom tend to gain only one electron?
It has 7 electrons in its valance shell so it needs only 1 electron to form a octet; the Nobel gas configuration.
In the compound sodium fluoride NaF the sodium atom loses one electron and the fluorine atom gains one electron to form ions that have electron configurations similar to?
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
Why does a potassium atom always lose its one valence electron what type of bond will it form with a chlorine atom?
A potassium atom "always" loses exactly one valence electron when it reacts with another element, because one valence electron in a potassium atom has a much lower ionization energy requirement than any other electron in the same atom. (This property is generally ascribed to the fact that when a potassium loses exactly one electron, it acquires the very stable electron configuration of the noble gas argon.) A chlorine atom has a very strong attraction (its electronegativity) for exactly one electron, which gives the charged atom the electron configuration of an argon atom. Therefore, when a potassium atom is close enough to a chlorine atom, one electron is transferred between to form an ionic bond and a formula unit of the compound potassium chloride.
What is the long form of the electron configuration of einsteinium?
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
Electron configuration for argon?
The electron configuration, in standard form, is [Ne] 3s2 3p6
What determines an atom behavior?
The largest determinant to an atom's behavior is its electron configuration. An atom's electron configuration determines its interactions with other atoms, such as which atoms it can form bonds with and whether that bond is covalent or ionic. Additionally, the number of neutrons and protons influence the stability of the atom's nucleus.

An ionic bond is one in which what shell electrons have been what?
an ionic bond is a bond formed when the electron in the outermost layer of an atom is given to another atom to "complete" the octet electron configuration of the receiving atom
What is the electron configuration for the fluorine atom?
1s^2 2s^2 2p^5 Note: The "^" symbol means the the following number is in the form of a superscript.
Why is the 2nd ionisation energy of Cr higher and not lower than of Mn?
The electron configuration of a neutral chromium atom is [Ar]3d54s1. The electron configuration for manganese is [Ar]3d54s2. The first electron removed from a chromium atom is the single 4s electron, leaving the electron configuration [Ar]3d5. The first electron removed from a magnesium atom is one of the 4s2 electrons, leaving the electron configuration [Ar]3d54s1. Removal of a second electron from a chromium atom involves the removal of one of the 3d electrons, leaving a configuration of [Ar]3d4, which is not a very stable configuration, and requires more energy to achieve. Removal of a second electron from a magnesium atom involves the removal of the second 4s electron, leaving a configuration of [Ar]3d5, which is more stable and requires less energy to achieve.
In the compound sodium fluoride NaF thev sodium atom loses one electron and the fluorine atom gains one electron to form ions that have electrons configurations similar to?
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
What happens to an atom of fluorine when it forms an ionic bond in which it has the same electron configuration as neon?
A fluorine atom gains one atom in order to achieve the same electron configuration as neon. In doing so, the fluorine atom forms a fluoride ion with a 1- charge with the formula F-. As a negatively charged ion, it can form ionic bonds with various positively charged ions.
Why does bromine form a -1 ion?
Bromine has seven electrons in its outermost energy level. It can get the stable electron configuration by getting one electron from another atom which makes the -1 charge.
