Positive. Metals 'lose' an electron during metallic bonding, this causes a sea of negative electrons throughout the metal molecules, leaving posotive metal ions
anion because they have -ve charge
metals and non-metals
Many different chemical species can form an ion with a plus 1 change. The most common example of cations of this type are the alkali metals, such as sodium and potassium.
net negative charge
Alkali metals forn cations with the chrage +1.
positive
+3 ion
Transition metals tend to form Type II ionic compounds due to their ability to exhibit variable oxidation states. These elements can lose different numbers of electrons to form ions with varying charges, leading to the formation of Type II compounds in which the metal ion has a specific charge.
Metals lose electrons to form positive ions, or also known as cations.
No, pure , real metals always form exclusively POSitive ions, binding in ionic compounds to non-metals (oxides, chlorides etc).
The pudding is delicious here try some yum!
A sulfur atom will gain two electrons to form a 2- sulfide ion.
