Answer:
K potassium have least ionization energy among these four
Explanation:
Ionization energy values are given in kilo joule per mole
Ca 590
Ge 762
K 419
Ga 579
From above data we can understand stand K has least and Ge has highest ionization energy
The lac repressor protein binds to the operator when it is active. The lac repressor is a protein or a DNA-bounding protein as it is called. The lac repressor also involves the lactose metabolism and it is also responsible for the transcription of three lac genes.
<span>4.5x10^22
Because there are 6.022x10^23 atoms per mole; therefore,
(6.022x10^23*(0.075)=04.5x10^22 atoms of titanium.</span>
Answer:
Explanation:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
