STEP 1

Assumptions1. The element contains15 electrons. . The element contains15 neutrons.
3. The atomic number of an element is equal to the number of electrons in a neutral atom.
4. The mass number of an element (represented in hyphen notation) is the sum of the number of protons (atomic number) and neutrons in the nucleus.
5. The hyphen notation for an element is written as Element-Mass number.

STEP 2

First, we need to determine the atomic number of the element. The atomic number is equal to the number of electrons in a neutral atom.
$Atomic\, number = Number\, of\, electrons$

STEP 3

Now, plug in the given value for the number of electrons to calculate the atomic number.
$Atomic\, number =15$

STEP 4

Next, we need to determine the mass number of the element. The mass number is the sum of the number of protons (atomic number) and neutrons in the nucleus.
$Mass\, number = Atomic\, number + Number\, of\, neutrons$

STEP 5

Now, plug in the given values for the atomic number and the number of neutrons to calculate the mass number.
$Mass\, number =15 +15$

STEP 6

Calculate the mass number.
$Mass\, number =15 +15 =30$

STEP 7

Now that we have the atomic number and the mass number, we can identify the element and write it in hyphen notation. The atomic number15 corresponds to the element Phosphorus (). So, the hyphen notation for the element is $Phosphorus-30$ The correct answer is "phosphorus-30".
