ionic compounds are held together by ionic bonds are formed by the transfer of electrons from a metal to a non metal
Ionic bond is formed by the electrostatic attraction between the oppositely charged ions.
metals give out electrons and becomes positively charged. positively charged ions are called cations. so these are called metal cations
the electrons given out are taken in by non metals and become negatively charged. negatively charged ions are called anions. then they are called non metal anions.
so ionic compounds are formed by the electrostatic attraction between metal cations and non metal anions.
therefore ionic compounds are composed of a metal cation and a nonmetal anion
Answer:
It should be used 2 digits to the right of the decimal point to report the result
Explanation:
When adding or subtracting two decimal numbers, the number of digits to the right of the decimal point in the result is equal to the amount with the least number of decimal places.
In this case we have 4 decimal places in 0.0136 g, 2 decimal places in 2.70 × 10-4 g and 2 decimal places in 4.21 × 10-3 g, so, the least number of decimal places is 2 and that should be the number of digits to the right of the decimal point in the result.
Then the result of the sum should be 9.66 × 10-3 g
I got 2.......................
Answer: the answer is B
Explanation:
Because they have to hold them to fill in their spaces.
b. electrons.
c. protons.
d. subatomic particles.
D. 6 electrons
A single nitrogen atom has five electrons in its outer energy level to start, and will be most stable with an octet, or 8 electrons in its outer level.
