1. CaS
2. Nitrogen forms an anion with a -3 charge.
3. S
4. Ca2N3
5. Mg3N2. Magnesium nitride
6. CaO. So 1,1
7. 2- O2- (2- is super scripted). It is also an anion, which is a negatively charged ion.
8. That would be aluminum iodide AlI3, also called aluminum triiodide.
9. LiCI
These should be correct. Hope I helped. ^~^
Idk 18 but here is 20
conductor-a substance that readily conducts
insulator-a substance that does not readily allow the passage of heat or sound
ammeter-an instrument for measuring electric current in amperes.
voltmeter- an instrument for measuring electric potential in volts
current-a flow of electricity which results from the ordered directional movement of electrically charged particles.
potential difference-the difference of electrical potential between two points.
ohmic resistor- resistors that have a constant resistance
non-ohmic resistor- a resistor that's resistance increases as the current increase
power-the capacity or ability to direct or influence the behavior of others or the course of events.
In an atom, the protons, which have a positive charge, and the neutrons, which have a neutral charge, are located in the nucleus. The electrons, which have a negative charge, orbit the nucleus of the atom.
If element A has an ionic charge of +2 and element B has an ionic charge of -3
then the reaction is given as: A^2+ + B^3- --------------------> A3B2
the compound formed is : A3B<span>2</span>
