Is br a anion or cation?
Bromine forms the Br- anion
When an element forms a negative ion what happens to its name?
When an element forms a negative ion, the name changes to IDE, fir example: chloride
What forms anion?
generally, non-metals
What forms an anion?
generally, non-metals
Does the atomic number of the element change when its atom forms ion?
No. Atomic Number is defined as the number of positive protons, and when a ion is formed(irrespective of cation or anion) only negative electrons will be lost or added hence the proton number is constant.
How does the size of the atomic radius in a nonmetal compare to size of its ionic radius?
I'm not positive but.... the ionic radius of a metallic atom is slammer than its atomic radius because metallic atoms want to loose electrons. The loss of electrons increases the pull of the nucleus, drawing the electrons closer and thereby making the ionic radius smaller than the atomic radius.
Is br a anion or cation?
Bromine forms the Br- anion
Is selenium cation or anion?
No. Selenium generally forms selenide (Se2-) ion
When an element forms a cation what happens to the radius and why?
The radius will decrease due to the positive charge of the nucleus drawing the electron cloud closer to itself
How do anion of nitrogen forms?
A nitrogen anion forms when a nitrogen atom gains three electrons, forming a nitride ion, N3-.
Does an anion always form a covalent bond?
No. An anion may contain covalent bonds, if it is a polyatomic anion, but an anion forms only ionic bonds if the anion's chemical integrity is maintained.
When an element forms a negative ion what happens to its name?
When an element forms a negative ion, the name changes to IDE, fir example: chloride
An ionic bond forms between?
Ions of opposite charge, cations and anions. Often these involve a metal cation and a non-metal anion but this is not always the case for example ammonium sulfate contains a poly atomic cation and a poly atomic anion and all of the elements present are non-metals.
Is scandium a cation OR anion?
