They have different masses because the number of neutrons varie. All these are called "isotopes". Each neutron weighs a certain amount, and with more or less neutrons, the mass changes

Is calcium oxide a covalently bonded compound or a ionically bonded compound?
Calcium oxide is an ionically bonded compound that contains equal numbers of calcium cations with a charge of +2 and oxide anions with a charge of -2.
How many numbers of electrons grained or lost for calcium?
2 electrons are lost from calcium, forming Ca2+ ion
How to write the formula for calcium chloride. Explain how you determined this formula?
Calcium's chemical symbol is Ca. Calcium's oxidation number is +2.Chloride's chemical symbol is Cl. Chloride's oxidation number is -1.Ca +2 Cl -1Ca 1 Cl 2 (Switch the two numbers)Ca1Cl2 HOWEVER if there's only one of an element, don't write the 1CaCl2
What is the oxidation number of Ca(NO3)2?
The sum of the oxidation numbers is zero for the compound.
Why does bromine have different mass numbers?
Bromine isotopes have different mass numbers because their atoms have different numbers of neutrons.
Is calcium oxide a covalently bonded compound or a ionically bonded compound?
Calcium oxide is an ionically bonded compound that contains equal numbers of calcium cations with a charge of +2 and oxide anions with a charge of -2.
How to explain making equivalent ratios?
Equivalent ratios are ratios that represent different numbers but the relationship between the numbers is same.
What is the same element whose nucleus contains different numbers of neutrons?
isotopes :D
Which statement about calcium is FALSE?
What are the choices?
Which subset of the real number system contains the most rational number and explain why?
The set of all rational numbers.If the set contains all of them then no other set can contain any more rational numbers.
Define the term isotope explain how two isotopes of an element are different?
Isotopes are atoms of the same element that have different numbers of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers. I hope I helped! ^_^
What are the quantum numbers of calcium?
2s,6p,
What is an element that has the same atomic number but different mass numbers?
If a sample of an element contains atoms of different mass numbers, the name of the element followed by a hyphen and the mass number is the name of an isotope of the element.
How do you half numbers?
How do you have numbers what. Can you explain better
Explain the square of the sum of two numbers is different from the sum of the squares of two numbers?
split 10 in two parts such that sum of their squares is 52. answer in full formula
How do you explain prime numbers in numbers?
A prime number is a positive integer that has exactly two different factors: 1 and itself. This is why 1 is not a prime number: it has the factors 1 and itself, but they are the same - it does not have exactly two different factors.
