What is the formula for valency?
The valency of an element is determined by the number of electrons it gains, loses, or shares to achieve a stable electron configuration. It is typically the same as the number of electrons an element needs to gain or lose to achieve a full outer shell (octet). For example, elements in Group 1 have a valency of +1 because they lose one electron to achieve stability, while elements in Group 17 have a valency of -1 because they gain one electron to achieve stability.
How many valence electrons does phosphorus need?
Phosphorus has 5 valence electrons and it needs 3 more electrons to complete its octet and achieve stability.
How many more electrons does nitrogen need to have a complete valence shell?
Nitrogen needs 3 more electrons to have a complete valence shell of 8 electrons. Nitrogen has 5 electrons in its valence shell, and a complete valence shell for nitrogen would have 8 electrons to achieve stability.
How many additional electrons is an oxygen atom able to attract?
An oxygen atom is able to attract 2 additional electrons to complete its valence shell and achieve a stable octet configuration. This is because oxygen has 6 valence electrons and needs a total of 8 electrons for stability.
How many electrons does O need to achieve noble gas?
Oxygen should gain 2 electrons to achieve noble gas configuration

What does a sulfur atom need to do to have a full valence level?
A sulfur atom needs to gain two electrons or share electrons with other atoms to have a full valence level. Sulfur has six valence electrons and can achieve stability by forming two additional bonds.
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.
How many additional electrons is an oxygen atom able to attract?
An oxygen atom is able to attract 2 additional electrons to complete its valence shell and achieve a stable octet configuration. This is because oxygen has 6 valence electrons and needs a total of 8 electrons for stability.
How many electrons does it take to fill outer shell of nitrogen?
Nitrogen has two energy levels. The first energy level contains two electrons. The second energy level contains five electrons. Number of Protons/Electrons: 7 Number of Neutrons: 7
How many electrons would a neutral atom of nitrogen need to lose in order to have a full valence electron shell?
A neutral atom of nitrogen (atomic number 7) needs to lose 3 electrons to have a full valence electron shell, similar to the nearest noble gas neon. This is because nitrogen has 5 valence electrons and needs 8 electrons in its outer shell to achieve stability.
How many electrons does nitrogen need to fill its outer shell?
Nitrogen needs 3 more electrons to fill its outer shell. It has 5 electrons in its outer shell, and it typically needs a total of 8 electrons to achieve a full outer shell (octet rule).
How many bonds does Br form?
Bromine (Br) can form one bond, as it has seven valence electrons in its outer shell and typically needs one more electron to complete its octet and achieve stability.
How many electrons does Mg need to be stable?
Magnesium (Mg) typically needs to lose 2 electrons to achieve stability, as it has 12 protons in its nucleus and aims to achieve a full outer electron shell like the nearest noble gas, neon. By losing 2 electrons, magnesium can attain a full valence shell of 8 electrons and become more stable.
How does the number of valence electrons affect an element?
The number of valence electrons determines an element's reactivity and ability to form chemical bonds. Elements with a full valence shell are stable and less likely to react, while elements with incomplete valence shells are more reactive and tend to form bonds to achieve stability.
