The answer to the problem 5 x (4 + 1) is called a C) product.
Given is an expression 5 x (4+1), we need to tell which mathematical operation dose it shows.
In mathematics, the term "product" refers to the result obtained when two or more numbers are multiplied together.
In this case, the numbers involved are 5 and (4 + 1). The expression (4 + 1) is first evaluated inside the parentheses, which results in 5.
Then, the multiplication is performed: 5 x 5 = 25.
So, the correct answer is C) product.

The electron configuration for each ion can be determined using the noble gas core notation.
The electron configuration for each of the given ions can be determined using the noble gas core notation. The noble gas notation involves representing the core electron configuration with the symbol of the noble gas that matches it, followed by the electron configuration of the valence electrons. For example, the electron configuration of a sodium ion ([Na]⁺) using the noble gascore notation is [Ne]3s².
