Question

Accepted Answer

# Explanation:
## Step1: Recall atomic number definition
The atomic number is the number of protons in an atom. For oxygen (O), the atomic number is 8.
## Step2: Recall atomic mass value
The atomic mass of oxygen given is 15.999.
## Step3: Determine number of protons
The number of protons in an oxygen atom is equal to its atomic number, so it is 8.
## Step4: Determine number of electrons in neutral atom
In a neutral atom, the number of electrons is equal to the number of protons. So for oxygen, the number of electrons is 8.
## Step5: Calculate number of neutrons
The number of neutrons = Atomic mass (rounded) - Number of protons. Rounding 15.999 to 16, number of neutrons = 16 - 8=8.

# Answer:
Atomic number = 8
Atomic mass = 15.999
# of protons = 8
# of electrons = 8
# of neutrons = 8

## Step1: Recall titanium's atomic number
Titanium (Ti) has an atomic number of 22. The number of protons is equal to the atomic number, so protons = 22.
## Step2: Calculate number of neutrons
Given mass number = 48. Number of neutrons = Mass number - Number of protons. So neutrons = 48 - 22 = 26.

# Answer:
Protons = 22
Neutrons = 26

## Step1: Calculate mass number
Mass number = Number of protons+Number of neutrons. Given protons = 87 and neutrons = 136. Mass number = 87 + 136=223.
## Step2: Identify element
The element with 87 protons is Francium (Fr).
## Step3: Calculate charge
Charge = Number of protons - Number of electrons. Given protons = 87 and electrons = 86. Charge = 87 - 86 = + 1.

# Answer:
Mass number = 223
Symbol = Fr$^{+}$
Charge = +1

## Step1: Identify element
The element with 37 protons is Rubidium (Rb).
## Step2: Write symbol and charge
Given 37 protons, 48 neutrons and 36 electrons. Charge = 37 - 36=+1. Symbol is Rb$^{+}$.

# Answer:
Name: Rubidium ion
Symbol: Rb$^{+}$

## Step1: Determine number of protons from symbol
For $^{93}$Nb$^{+3}$, the atomic number of Niobium (Nb) is 41, so protons = 41.
## Step2: Calculate number of neutrons
Mass number = 93. Number of neutrons = Mass number - Number of protons. So neutrons = 93 - 41 = 52.
## Step3: Calculate number of electrons
Charge = + 3. Number of electrons = Number of protons - Charge. So electrons = 41-3 = 38.

# Answer:
Protons = 41
Electrons = 38
Neutrons = 52

## Step1: Determine number of protons from symbol
For $^{141}$Ce$^{+4}$, the atomic number of Cerium (Ce) is 58, so protons = 58.
## Step2: Calculate number of neutrons
Mass number = 141. Number of neutrons = Mass number - Number of protons. So neutrons = 141 - 58 = 83.
## Step3: Calculate number of electrons
Charge = + 4. Number of electrons = Number of protons - Charge. So electrons = 58 - 4=54.

# Answer:
Protons = 58
Electrons = 54
Neutrons = 83

## Step1: Identify element
The element with atomic number 7 is Nitrogen (N).

# Answer:
ii) N

## Step1: Determine number of electrons in neutral atom
For an atom with atomic number 7 (nitrogen), in a neutral state, the number of electrons is equal to the atomic number. So electrons = 7.

# Answer:
ii) 7

## Step1: Recall copper's atomic number
Copper (Cu) has an atomic number of 29. In a neutral atom, the number of electrons is equal to the atomic number. So electrons = 29.

# Answer:
iv) 29

## Step1: Calculate atomic mass
Atomic mass (in amu) = Number of protons+Number of neutrons. Given protons = 14 and neutrons = 14. Atomic mass = 14 + 14=28.

# Answer:
ii) 28
