In the periodic table, the group number or elements belonging to the same column are elements with the same charge relating to the number of valence electrons which can react with other atoms in their outside shells. In this case, the positive charges pertain to B. group number.

Answer: The group number.

The group number in the modern periodic table shows the number of valence electrons (or ions) in the outermost shell of an atom. [The valency is the number of electrons present in the outermost shell that is needed to be eliminated or added from outermost shell of an atom to complete its octate. It is defined for atoms for neutral charges while charge (ions) is defined for charged species].

Therefore, Alkali metals, alkaline earth metals, and aluminum all form ions with positive charges equal to the group number.

If f(x) = x2, which of the following describes the graph of f(x - 1)? A. The graph of f(x - 1) is a horizontal shift of f(x) = x

pantera1 [17]

Answer:

Step-by-step explanation:

To understand this, we can look at the vertical & horizontal translations of a parabola of the form $f(x)=x^2$

A vertically translated parabola has the form $f(x)=x^2+k$ , where k is the vertical shift upward when k is positive and vertical shift downward when k is negative.
A horizontally translated parabola has the form $f(x)=(x-a)^2$ , where a is the horizontal shift rightward when a is positive and horizontal shift leftward when a is negative.

When we replace x of the original function with (x-1), we have $f(x)=(x-1)^2$ . According to the rules, this means that the original function is shifted 1 unit right (horizontal shift).

Correct answer is A.
