mole=10 x 10⁻³ : 46 g/mol = 2.17 x 10⁻⁴
Answer:
A meteor hit earth they think the moon is created from debris from earth but really God created it UwU
Explanation:
We know that the element Z = 119 would be placed right below the Fr, in the column of the alcaline metals.
We also know that the trend in the electronegativity is to decrease when you go up-down ia group.
The known electronegativities of the elements of this group are:
Li: 0.98
Na: 0.93
K: 0.82
Rb: 0.82
Cs: 0.79
Fr: 0.70
Then the hypotetical element Z = 119 would probably have an electronegativity slightly below 0.70, for sure in the range 0.60 - 0.70.
Explanation:
Scientifically speaking, metals are naturally occurring chemical elements that are typically hard, lustrous, and good conductors of both heat and electricity. Examples include iron, gold, silver, copper, zinc, nickel, etc., but also elements we don't normally think of as metals.
Answer:
sodium atoms are much larger than chlorine atoms but in case of sodium ions they are much smaller thqn chlorine ions
