a group that forms anions with a -1 charge
Only chemical elements are placed in the periodic table; cations are positive charged atoms.
A polyatomic ion is a group of atoms with a charge.
How to determine these ions:metal cations: find the positive charge, and make sure it is qual to the group numbernonmetal anions: subtract 8 from the group numbertransition metals cations: the number of electrons lost
Going across the periodic table from left to right ignoring the transition metals, +1 charge are for group IA, group IIA is for +2 then it skips to group IIIB with +3 charge, group VB is -3, group VIB is -2, group VIIB is -1 charge.
Group IA: +1 charge Group II2: +2 charge Group IIIB: +3 charge Group IVB: +4 charge Group VB: -3 charge Group VIB: -2 charge Group VIIB: -1 charge
they are the cations
Group 3 and lanthanides.
Only chemical elements are placed in the periodic table; cations are positive charged atoms.
Group 2, alkali earth metals.
Elements from the group 2 of the periodic table form cations.
Ions are formed when atoms have charges. Cations are species with positive charge. Anions are species with negative charge.
These cations have the electrical charge +1.
A polyatomic ion is a group of atoms with a charge.
Cations and anions are different types of ions.A cation is a positively charged atom or group of atomsA anion is a negatively charged atom or group of atomstotal positive charge of cations = total negative charge of anions
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
