How do you name ionic compounds?
ryzh [129]

Answer:

Consult the periodic table of elements

Explanation:

When naming ionic compounds, all of the information you’ll need is on the periodic table. Ionic compounds are formed of a metal (cation) and a non-metal (anion). You can find metals on the left and central sections of the periodic table (e.g., Barium, Radium, and Lead), while you can find non-metals on the right side of the table.[1]

Svetlanka [38]

Base unit is the fundamental unit of measurement that is not mutually dependent. The seven base units are,

Length - meter

Mass- kilogram

Time - second

Temperature - Kelvin

Current - Ampere

Luminous intensity - Candela

Amount of matter - mole

Derived units are derived from the seven base units. Like the area (square meters) is the square of length (meters), volume is the cube of length.

Not A.

Not C. Do you like yogurt? If you don't do you know someone who does? Is yogurt for you/them a bad thing. Bacteria here are good. Again, not C.

Not D. Waste is bad. It's a problem. Getting rid of it is good. Again not D.

There's only one left.
B <<<< answer. Who would like to get strep throat. It's a fate for your worst enemy.

B <<<< answer.
