How many atoms of chloride are in 654.5 grams of calcium chloride?
To find the number of chloride atoms in 654.5 grams of calcium chloride, you would first calculate the number of moles of calcium chloride using its molar mass. Then, since each formula unit of calcium chloride contains two chloride ions, you would multiply the number of moles by 2 to find the number of chloride atoms.
What do you call atoms of the same element such as Chlorine which have the same number of protons but different number of neutrons?
Isotopes.
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.
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.
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.
What is the difference between calcium and calcium chloride?
Calcium chloride contains only two elements, calcium and chlorine, while calcium chlorate contains these two elements plus oxygen. The chlorine and oxygen in calcium chlorate are combined in a polyatomic ion with formula ClO3-1.
How many atoms of chloride are in 654.5 grams of calcium chloride?
To find the number of chloride atoms in 654.5 grams of calcium chloride, you would first calculate the number of moles of calcium chloride using its molar mass. Then, since each formula unit of calcium chloride contains two chloride ions, you would multiply the number of moles by 2 to find the number of chloride atoms.
What are facts about isotopes of the same element?
Isotopes of the same element have a different number of neutrons.
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.
What are element that differ in the number of neutrons known as?
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
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 = =
Do isotopes have the same A number?
The atomic number is the same for the isotopes of a chemical element.
