When metal atoms combine chemically with atoms of other elements, what do they usually do?
Fiesta28 [93]

Answer:

Maybe I know too much chemistry but how the metals (and the non-metals) react depends on where they are in the Periodic Table. The metals in groups I and II over on the far left side are explosively reactive and loose electrons and form ionic bonds. Examples: Na+1 has lost 1 electron and Li+2 has lost 2 electrons. The metals in the higher groups are more confusing but most of them share outer shell electrons and form covalent bonds. Examples: Fe2O3 (rust) where Iron shares 2X3 electrons with Oxygen which shares 3X2 electrons. Confused enough? :-)

The answer you'll be expected to give depends on the subject of the chapter you're studying. If you're studying covalent bonds, then the answer will probably be "form covalent bonds". If you're studying ionic bonds, then the answer will be "lose electrons".

Explanation:

This may not be the answer... I'm sorry if it's not

At 170C, a sample of hydrogen gas occupies 125cm3. What will be the volume at 1000C? =161cm3 If the volume of a given mass of ga
pickupchik [31]

1. V= 161

2. V = 37.3

<h3 /><h3>Further explanation  </h3>

Charles's Law states that  

<em>When the gas pressure is kept constant, the gas volume is proportional to the temperature  </em>

\tt \dfrac{V1}{T1}=\dfrac{V2}{T2}

1.

\tt \dfrac{125}{17+273.15~K}=\dfrac{V2}{100+273.15}\\\\V2=160.7\rightarrow 161~cm^3

2.

\tt \dfrac{27.3}{0+273.15`K}=\dfrac{V2}{100+273.15}\\\\V2=37.3~cm^3

Potassium carbonate (K2CO3) has one potassium atom bonded to carbon, and that carbon is also bonded to three oxygens. Their elec
dybincka [34]

Answer:

I'm not all the way sure but I think it is C

Explanation:

The reason is because an ionic bond essentially donates an electron to the other atom participating in the bond. Also, the C-O I think is polar since it is evenly distributed.
