Is floride a non metal or a metal?
Fluoride is neither, it is an ion that cannot exist on its own as a substance because it is electrically charged. Fluorine is a non-metal.
Is it true that in chemical reactions metal atoms usually become positively charged ions?
Yes,as they have mobile electrons which can be easily donated to other atom .also ionization energy is low
What do metals become after the donate electrons?
Metal --> electrons + Metal ions (positively charged)
What type of ion is formed by metal atom?
Cations, positively charged
What does the term base or parent metal in an alloy mean?
base metal: a metal that oxidises or corrodes easily and i dont know what parent metal is..
If you rub a coin briskly between your fingersit will not seem to become charged by frictionwhy?
because coin is made up of insulated metal thats why coin cannot charged
Would a negatively charged balloon stick to a metal wall as easily as to a wooden wall?
Yes, because metal conduct electricity.
Is floride a non metal or a metal?
Fluoride is neither, it is an ion that cannot exist on its own as a substance because it is electrically charged. Fluorine is a non-metal.
Why only one end of metal rod cannot be charged?
Metal is a good conductor. Any charge will quickly be distributed over the entire metal piece.
Is potassium unlikely to form a positively charged ion?
No, potassium, as a metal, very easily forms a positive ion.
Is sodium easily burn with a small flame in air?
The sodium is alkali metal it cannot be easily burn in a small flame
How does oil reduce air friction?
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
Why can't a non conducting material be charged easily by rubbing?
I don't think there is such a thing as a "non-conducting metal". All metals are good conductors.
How ball bearing reduce friction?
Bearings reduce friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. The smoothness of the metal reduces the friction and the surface area.
Why is alkali metal different to other metals?
because it has so many orbitals it has more electrons and it cannot hold onto its electrons as easily and they can easily be snatched away
How do you recognize the difference between the ion charge of a metal and the non metal?
Metal ions are typically positively charged, while nonmetals are typically negatively charged.
How does lubrication protect a cars engine?
It prevents high friction metal-on-metal contact.
