Question

question 9
identify the parts below for $_1^1h^{+1}$.
atomic number
mass number
protons
neutrons
electrons
charge
element name
type of ion

Explanation:

Step1: Recall atomic notation rules

In the notation $_{1}^{1}H^{+1}$, the sub - script represents the atomic number.

Step2: Identify atomic number

The atomic number ($Z$) of hydrogen is 1, so the atomic number is 1.

Step3: Identify mass number

The mass number ($A$) is the superscript before the element symbol. Here, the mass number is 1.

Step4: Determine number of protons

The number of protons is equal to the atomic number. So, the number of protons is 1.

Step5: Calculate number of neutrons

Number of neutrons = Mass number - Atomic number. So, $1 - 1=0$.

Step6: Determine number of electrons

Since it is a $+ 1$ ion, number of electrons = number of protons - charge. So, $1-1 = 0$.

Step7: Identify charge

The charge is $+1$.

Step8: Identify element name

The element is hydrogen.

Step9: Identify type of ion

It is a cation (a positively - charged ion).

Answer:

Atomic Number: 1
Mass Number: 1
Protons: 1
Neutrons: 0
Electrons: 0
Charge: +1
Element Name: Hydrogen
Type of Ion: Cation
