Is a positively charged ions are a referred to as a contion?
Positively charged ions are called CATIONS
What is cations?
Positively charged ions.
What is cation and anion?
Cations are positively charged ions. Anions are negatively charged ions. An ion is just an atom with either more electrons than protons (so it would be negatively charged... an anion), or fewer electrons than protons (so it would be positively charged... a cation). It should be noted that not all ions are single atoms. You can have polyatomic (many atom) anions (like SO42-) or cations (like NH4+). These are just molecular compounds that have charge because they have gained or lost electrons.
Is an ion is a charged particle?
yes. negatively charged ion is called cation and where as a positively charged ion is anion.
Is radioactive uranium positively charged?
The alpha radiation emitted from uranium isotopes is an ionizing radiation.
What is a polyatomic number?
There is no such thing. There are polyatomic ions, which are positively or negatively charged, covelantly bonded groups of atoms, though.
How are polyatomic ions usually charged?
It depends but most are negative, e.g. nitrite, sulfate, nitrate, sulfite, chlorite, phosphate, phosphite, permanganate, chromate, dichromate etc. There are however, polyatomic ions that are positively charged.
Is a positively charged ions are a referred to as a contion?
Positively charged ions are called CATIONS
Is uranium positively charged?
Ions of uranium (cations) are positively charged.
What are cation ions?
Positively charged ions
Is Barium unlikely to form positively charged ions?
yes, Barium is unlikely to form positively charged ions.
What is cations?
Positively charged ions.
Which type of ions are charged substances that contains more than atom?
polyatomic ion
What is cation and anion?
Cations are positively charged ions. Anions are negatively charged ions. An ion is just an atom with either more electrons than protons (so it would be negatively charged... an anion), or fewer electrons than protons (so it would be positively charged... a cation). It should be noted that not all ions are single atoms. You can have polyatomic (many atom) anions (like SO42-) or cations (like NH4+). These are just molecular compounds that have charge because they have gained or lost electrons.
Is an ion is a charged particle?
yes. negatively charged ion is called cation and where as a positively charged ion is anion.
What group of elements on the periodic table lose one electron to combine?
The atoms of the group 1 elements, called the alkali metals, lose one electron and form positively charged ions in order form ionic compounds with negative ions of nonmetals, or negatively charged polyatomic ions.
Are positively and negatively charged atoms?
No, ions are.
