Is force that holds two atoms together

• Chemical bond

• Physical bond

• American bond

• SSPSPSDPSDPSDPSFDPSsFDP

Cation is

• A positively charged ion that loses one or more valence electrons to attain a noble gas configuration

• A positively charged ion that loses one or more valence electrons to attain a pseudo noble gas configuration

• A negatively charged ion that loses one or more valence electrons to attain a noble gas configuration

• A positively charged ion that loses one valence electrons in all times to attain a noble gas configuration

metals are

• Metal atoms are reactive because they loose valence electrons easily

• Metal atoms are reactive because they loose valence electrons hardly

• Metal atoms are unreactive because they loose valence electrons easily

• Mohammed sabiq

When forming positive ion ,transition metals always loose two valence electrons

• True

• False

Looses electrons to form an outer energy level containing full S,PD suplevels,

And the last energy level contains 18 valence electrons

• Pseudo noble gas

• Noble gases

• Marron

• Carbon gases

Nonmetals have always negative ions

• True

• False

Anion is a negatively charged ion that gains valence electrons!!

• True

• False

When chlorine atom gains one valence electron how it would be named?

• Chlorine anion

• Chlorine hasaneen

• Chloride ion

• Chlorine atom

The Electronegativity force that holds oppositely charged particles together in an ionic compound “contain ionic bond” is referred to as ionic bond

• True

• False

If ionic bonds occur between metals and nonmetals oxygen oxides form

• True

• False
