Is the number of protons in an atom determines its atomic number
Chromium is a metal. Atomic number of it is 24.
To count the number of elements in a compound, you can identify the different elements present by looking at the chemical formula. Each element is represented by a unique symbol (e.g., H for hydrogen, O for oxygen). Count the number of unique elements present in the compound to determine the total number of elements.
An atom with an atomic number of 9 means it has 9 protons. The atomic mass of 19 indicates the total number of protons and neutrons in the nucleus, so if the atom has 9 protons, the remaining mass comes from neutrons (19-9=10 neutrons).
In order of increasing atomic number. Periods tell energy levels. Groups tell number of valence electrons. -PainRain
Yes, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral. If an atom has a different amount of protons and electrons it is electrically charged, and is called an ion, rather than an atom.
Hydrogen has the atomic number of 1.
Aluminum (Al)
Li is atom number three, not only 'was' but it still is and ever will be.
Atomic not Atomis!
the answer is 107.87
The atomic number tells you the number of protons the atom of an element has. The atomis is the smaller of the two numbers next to symbol of the element.
Atomis
No, the Atomic Mass is the full complete mass while the mass # is just the whole number. For example: carbon's atomis mass is 12.011 and the mass # is 12.
average atomis mass
Chromium is a metal. Atomic number of it is 24.
Neon
As the tern neutral might imply, the overall charge of a neutral atomis zero.
