Among the elements Barium has the lowest Ionization Energy.
<h3>What is Ionization Process ?</h3>
The process by which any neutral atom gets converted into electrically charged by gaining or losing electron is called Ionization Process.
K is an alkali metal it has to lose one electron to attain stable electronic configuration of an inert gas
For removing second electron , a stable configuration has to be broken and so will require high amount of energy.
Ca and Ba are alkaline earth metals.
They both have to lose 2 electrons to attain stable electronic configuration of noble gas.
They have low Iow Ionization Energy as compared to K.
Ca has higher Ionization Energy as compared to Ba because when we move down the periodic table , The ionization energy decreases.
Hence , Among the elements Barium has the lowest Ionization Energy.

Answer:
50.0 moles C02
Explanation:
First write down the CORRECTLY balanced equation. NOTE: The equation you provide is incorrect.
2C2H2(g) + 5O2(g) ==> 4CO2(g) + 2H2O(g) CORRECT EQUATION
Next, look at the stoichiometric ratio of C2H2 to CO2. You can see it is 2 moles C2H2 produces 4 moles CO2.
Thus, 25.0 moles C2H2 x 4 moles CO2/2 moles C2H4 = 50.0 moles CO2
Answer:
The answer to your question is:
Explanation:
3.- Convert each into
1.56 x 10⁴ = 15600
0.00259 x 10⁵ = 259
0.00259 x 10³ = 2.59
0.56 x 10⁻² = 0.0056
0.000459 x 10⁻¹ = 0.0000459
0.0209 x 10⁻³ = 0.0000209
3.69 x 10⁻² = 0.0369
13.69 x 10⁻² = 0.1369
736.9 x 10⁵ = 73690000
6.9 x 10⁴ = 69000
4.- Calculate the following
a) 2653000 = 2.653 x 10⁶
b) -2687 = - 2.687 x 10³
c) 2.532 x 10²⁴
d) 1470 = 1.47 x 10³

Answer:
Like charges repel
and opposite charges attract each other
lonic bonds are formed when ions attract
each other
Explanation:
An electrical charge can be either positive or negative. Two positive charged atom can never combine as they experience strong nuclear repulsive force Like wise two negatively charged atom can never combine as they repel each others negative electrostatic field.
An ionic bond is formed between two atoms in which one is electron deficient and other has surplus electron.
The atom with surplus electron is negatively charged and the atom with deficient electron is positively charged and thus these two oppositively charged atoms attract each other
