The ionic charges of group 1 and 2 metals are +1 and +2 respectively. Group 15 & 16 the simple mono-atomic ions are -3 and -2. Group 17 ions are -1. This can be explained by the following elemnts in groups 1 and 2 lose 1 or 2 electrons respectively to achieve a noble gas configuration whereas groups 15, 16 and 17 gain electrons (3,2 1 respectively)

What charge would an ion have based on its group?
1: 1+ 2: 2+ 13: 3+ 14: 4+/- 15: 3- 16: 2- 17: 1- 18: Neutral Transition metals (elements between groups 2 and 13) are able to have varied charges that there is no real rule for.
What elements can form more than one different ion?
Transition elements are the major group of elements with this property.
What group has an oxidation number of -3?
Group 15 elements, also known as the nitrogen group, typically have an oxidation number of -3 when they form ions. This group includes elements such as nitrogen, phosphorus, arsenic, antimony, and bismuth.
What groups are nitrogen xenon and cesium found?
Nitrogen is found in group 15, xenon in group 18, and cesium in group 1 on the periodic table.
Why are groups 14 and 15 better representatives of mixed groups than are group 13 or group 16?
Groups 14 and 15 on the Periodic Table feature elements which are metals, non-metals, and metalloids.
What elements tend to lose electrons and form positive ions while which elements tend to gain electrons and form negative ions.?
Elements that tend to lose electrons and form positive ions, known as cations, are typically metals, especially those in groups 1 and 2 of the periodic table, such as sodium and calcium. These elements have a low ionization energy, making it easier for them to lose electrons. Conversely, nonmetals, particularly those in groups 15 to 17, like chlorine and oxygen, tend to gain electrons to achieve a full outer shell, forming negative ions known as anions. Their higher electronegativity facilitates the gain of electrons.
How can you tell what type of ion an atom will form by looking at the periodic table?
elements which have 1 to 3 valence electrons will generally lose electrons and form cations. elements which need 1 to 3 electrons to attain the nearest noble gas configuration will generally gain electrons and form anions
What rule of thumb is used to determine to charge on non metal ions?
Non-metal ions typically have a charge that corresponds to the number of electrons they need to gain to achieve a stable electron configuration, usually by gaining enough electrons to fill their outermost energy level. For example, elements in Group 15 usually gain three electrons to form ions with a 3- charge, while those in Group 17 usually gain one electron to form ions with a 1- charge.
What charge does group 15 have when it forms ions?
They generally form covalent compounds, but still they form -3 valency ions.
What charge would an ion have based on its group?
1: 1+ 2: 2+ 13: 3+ 14: 4+/- 15: 3- 16: 2- 17: 1- 18: Neutral Transition metals (elements between groups 2 and 13) are able to have varied charges that there is no real rule for.
What category do groups 1-12 in the periodic table fall under?
Groups 1-12 on the periodic table are known as the "main group elements" or "representative elements." These groups include elements with varying chemical properties and are found in the s and p blocks of the periodic table. They are important for forming compounds and ions with different valences.
What type of ethnic groups are in Somalia?
85% Ethnic Somalis, 15% Non Ethnic Somalis( Bravanese Somalis, Bantus, Bajunis)
Is group fifteen an ionic compound on the periodic table?
Group 15 elements generally form covalent compounds. However the two elements from group 15 nitrogen and phosphorus are known to form nitride (N3-) and phosphide (P3-) ions as in Na3N or Na3P.
3 groups of 5 is?
15
What groups are nitrogen and oxygen in?
Groups 15 and 16, respectively.
What are the charges for the main group elements?
Main group metals tend to lose electrons, forming a cation with the same number of electrons as the nearest noble gas. A main group nonmetal tends to gain electrons, forming an anion with the same number of electrons as the nearest, previous noble gas
What groups of elements always combine to make ionic compounds?
All metals combine to form ionic compounds.Group 1(except hydrogen),2-12, all elements form ionic compounds.then Group 13 (except Boron), Group 14-tin and lead and Group 15 Bismuth only.The above mentioned group elements form ionic compounds.
