How many electrons does Group 15 lose or gain?
The group 15 elements consist of five valence electrons. Due to this the elements can either lose five electrons or gain three electrons in order to attain the stable configuration.
How many electrons will sodium lose to become stable?
one valence electron
A neutral sodium atom is likely to achieve an octet in its outermost shell by losing its one valence electron.
How many electrons do Group 15 elements need to form octet?
Answer and Explanation: Elements that belong to Group 15 all have 5 electrons in their valence shell. According to the octet rule, atoms prefer to have 8 valence electrons in…
How many electrons will sodium gain?
Tell students that when an atom gains or loses an electron, it becomes an ion. Sodium loses an electron, leaving it with 11 protons, but only 10 electrons. Since it has 1 more proton than electrons, sodium has a charge of +1, making it a positive ion.
How many valence electrons are in an atom of group 15?
5
The number of valence electrons
| Periodic table group | Valence Electrons |
|---|---|
| Group 14 (IV) (carbon group) | 4 |
| Group 15 (V) (pnictogens) | 5 |
| Group 16 (VI) (chalcogens) | 6 |
| Group 17 (VII) (halogens) | 7 |
How will sodium become stable?
Sodium would become stable if it could lose an electron and attain the configuration of neon (2,8). Every atom has the tendency to acquire the configuration of the nearest noble gas and become stable.
Why is sodium ion stable?
Sodium loses its outermost electrons, when it loses it acquires Octet configuration (eight electrons in outermost shell) so that it gets stability.
How many bonds do group 15 elements form?
three covalent bonds
Group 5A (15) elements such as nitrogen have five valence electrons in the atomic Lewis symbol: one lone pair and three unpaired electrons. To obtain an octet, these atoms form three covalent bonds, as in NH3 (ammonia).
What are Group 15 elements called?
nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
Is sodium stable or unstable?
This is a very unstable arrangement, and the element sodium is a highly reactive, deadly white semi-solid that will burst into flames on exposure to the air or will burn through human flesh on contact. A reactive substance.
How many valence electrons does group 15 have?
Why are sodium ions stable?
Sodium (+1) ion has the noble gas configuration, which means their outermost shell are completely filled with electrons. That’s why Sodium ion is not reactive (means stable). The atom of sodium has one electron in its outermost shell.
How many electrons does sodium lose when making a chemical bond?
3 s electrons
After the transfer of electrons, sodium loses 3 s electrons and becomes sodium ions (Na+), while the chlorine element gains an electron and becomes chlorine ions (Cl−) [8]. Figure 4.2.
How is sodium stable?
When Sodium loses one electron it acquires nearest noble gas configuration (Neon-configuration with number of electrons=10). Sodium loses its outermost electrons, when it loses it acquires Octet configuration (eight electrons in outermost shell) so that it gets stability.
What are the properties of Group 15 elements?

How many valence electrons are in an atom of each element in Group 15?
How do you make sodium stable?
What are the oxidation states of the elements in Group 15?
The oxidation state +2 is known in all the elements in compounds containing element-element bonds. For example: The main oxidation states for group 15 are -3, +3, and +5. We may also add 0 (elementary substances).
What is the reactivity of Group 15 elements?
Reactivity towards Metals All the elements of group 15 combine with metals to form their binary compounds in which the elements show -3 oxidation state. For example: N itrogen forms nitrides (Mg 3 N 2 : magnesium nitride, Ca 3 P 2 : calcium nitride)
Why are neutral covalent compounds of the group 15 called Lewis bases?
Because neutral covalent compounds of the trivalent group 15 elements have a lone pair of electrons on the central atom, they tend to be Lewis bases. Reactions and Compounds of Nitrogen
What is the outermost E-config of Group 16 elements?
The outermost e- config of group 16 elements is ns2 np4. Group 16 elements exhibit +4 oxidation when they lose 4 electrons from p orbital and they exihibit +6 oxidation state when they lose 4 electrons from the outermost p orbital and 2 electrons from the s orbital.
