When you put an element in a flame you see different colors of light given off How why?

The heat of the flame provides thermal energy which can excite the electrons in the atom to higher energy levels. When the electrons 'relax' down to their ground state the excess energy is given out as radiation. For it to be coloured, the radiation must fall in the visible spectrum.

What do atoms of the same given element share?
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
What is the atomic number in a given element equivalent to?
The atomic number in a given element is equivalent to the number of protons in the element.
How are isotopes the same but different?
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
Is it possible for atoms of the same element to have different chemical properties?
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
What is the visible substance -given off by a burning object?
flame

What are atoms of a given element that have a different number of neutrons?
Isotopes.
Uses of flame tests in industry?
There are a few different applications of a flame test. These applications include testing for specific chemicals, checking some items specifically for poisonous chemicals, and testing fireworks.
Do the nuclei of all atoms of a given element always have the same number of neutrons?
No - different isotopes of an element have different numbers of neutrons. All atoms of an element will have the same number of protons.
What number identify an element?
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
What is the atomic emission spectra?
The colors of light given off when an element loses energy
What kind of flowers were given to the athelets at the Olympics?
Different contries have different colors of flowers. For example, spidermoms and hypericum berries.
What does every atom in a particular element have in common?
They all have the same number of neutrons. All atoms of a given element have a specific number of protons. That is what gives an element its elemental identity. But we know that different atoms of a given element can have different numbers of neutrons. These different atoms of the same element are the isotopes of that element. All the atoms of a given isotope of a given element will have the same number of protons and will have the same number of neutrons. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties.
How do the isotopes of a given element differ from another?
In that they have different masses due to difference in neutrone number
What was Dalton's four proposals or therories?
Elements are made of tiny particles called atomsAll atoms of a given element are identical (Proven wrong)The atoms of a given element are different from any other element (Not completely true)Atoms of one element can combine with atoms of another element to form chemical compounds
What elements under fire produce green and violet colors?
In flame test,Apple green color is given by Barium.Copper also gives a green color.Pottasium gives a pale purple color.
What are practical application of flame test?
The flame test as a chemical test is rarely used as a diagnostic anymore. It has been replaced with ICP (Inductively Coupled Plasma) analysis that is basically a computerized flame test on steroids. ICP analysis allows researchers to quickly determine the elemental composition of almost any sample. One fun application of the flame test is fireworks. Fireworks are given their colors by the same chemicals that color flames in the flame test.
