What is the number of protons and neutrons in a calcium nucleus?
The atomic number of calcium is 20 and relative atomic mass (nucleon number) 40.1. The nucleon number is a decimal because it is an average value having taking all the different isotopes into consideration, based on their relative abundance. So all calcium atoms have 20 protons and 20 electrons. The number of neutrons will depend on what isotope of calcium we are talking about; calcium has 24 isotopes. If we consider the isotope calcium-40, which is the most abundant of all at about 97%, the can determine its number of neutrons as 40 - 20 = 20. So a calcium-40 isotope has 20 neutrons.
Which isotopes of uncharged elements have different numbers?
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
What you mean when you say that a particular element consists of several isotopes?
All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons. Atoms with the same number of protons but different numbers of neutrons are called isotopes. An element has many isotopes--each with a close, but different number of neutrons.
What is the atomic number of calcium sulfate?
Atomic number is a property of an atom (An Element) and not a chemical compound. Sodium chloride is a compound and thus it can not have any atomic number. Atomic number is the number of protons present in the nucleus of the atom of an element. e.g. Carbon has six protons in its nucleus, therefore its atomic number is six. However, sodium chloride has two different elements as its constituents and therefore one can not determine its atomic number.
Which element has a mass number of 40 and only has 2 valance electrons?
The element that has a mass number of and two valence electrons is an isotope of calcium.
Is calcuim a mixture?
Only of isotopes. Calcium is an element. No mixture of chemicals can ever be a single element. The atoms of any element, such as calcium, always have the same number of protons and the same number of electrons. The number of electrons in an atom is the same as the number of protons in that atom. Different Isotopes of an element have different numbers of neutrons in the nucleus, but this doesn't change any of the chemical properties.
How many neutrons calcium?
The number of neutrons is the difference between the Atomic Mass of an isotope and the atomic number of the element; each isotope of calcium has a different number of neutrons. See the link below for calcium isotopes.
How many aoms of each element are present in calcium chloride?
Calcium is one element, and chloride is the element to make up the structure of calcium chloride, which is CaCl2.By the molecular formula, we see that there are two chloride atoms and one calcium atom in one molecule of calcium chloride. This means that there are two times as many atoms of chloride than calcium in the structure.If nothing else is stated, the number of moles is always equal to 1 for any element. One mole is equal to 6.022 x 1023 atoms. There are thus:1×(6.022 x 1023)=6.022 x 1023 atoms of calciumand2×(6.022 x 1023)≈1.2 x 1024 atoms of chloride
What element has 20 protons and is found in teeth and bones?
Calcium
How does an element differ from its isotopes?
Isotopes of the same element have different number of neutrons.
Two isotopes of the element rubidium differ in their number of protons?
no isotopes of a particular chemical element all have the same number of protons
Can isotopes of an element have the same number of neutrons?
Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same number of neutrons.
What are facts about isotopes of the same element?
Isotopes of the same element have a different number of neutrons.
Isotopes of an element differ from each other in the number of?
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
How do the atomic number of the different isotopes an element compare?
The atomic number is the same for the all isotopes of a chemical element.
If you have 2 atoms have the same number of protons but different number of neutrons what will they will have the same?
No, they will not be considered isotopes since isotopes are atoms of same element (therefore, have same number of protons). However, the types of atoms which have same atomic mass number but different no. of protons, they are called isobars. Eg:- Calcium and Argon = =
What are element that differ in the number of neutrons known as?
Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.
