The more electronegativity atom attracts electrons more strongly and gains a slightly negative charge, the less electronegative atom has a slightly positive charge.

Explanation:
Answer:
When you use a machine, you apply force to the machine. This force is called the input force. The machine, in turn, applies force to an object. This force is called the output force.
Answer:
0.7692 M ≅ 0.77 M.
Explanation:
- It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 2.0 M, V before dilution = 0.25 L.
M after dilution = ??? M, V after dilution = 0.25 L + 0.40 L = 0.65 L.
∴<em> M after dilution = (MV) before dilution/(V) after dilution</em> = (2.0 M)(0.25 L)/(0.65 L) =<em> 0.7692 M ≅ 0.77 M.</em>
Answer:
The correct answer is: d-orbital
Explanation:
The transition metals are the chemical elements that belong to the B-group of the periodic table, from group 1B to 8B. The B-group is located between the groups IIA and IIIA in the periodic table.
The general electronic configuration of the chemical elements belonging to this group is (n-1) d¹⁻¹⁰ ns⁰⁻², because of the <u>partially filled d-subshell</u> in the ground state or excited state. <u>Therefore, the transition metals are refereed as the </u><u>d-block elements</u><u>.</u>
