Which minerals on the periodic table is made up of two elements?
The periodic table lists element and not minerals.
Where is hydrochloride on the periodic table?
It isn't on the periodic table since it is not a single element but a compound made of two elements: hydrogen and chlorine.
What element is 2nd in the periodic table?
The second element is element number two: Helium
What is the atomic mass on the periodic table?
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
What is an element in group 2 of the periodic table?
Calcium, Magnesium, and Radium are all in group two of the periodic table.
The first element on the periodic table table of elements is helium?
No, the first element on the Periodic Table is Hydrogen, but because of its unusual behaviour it is usually placed by itself, not next to any other elements. The second element is Helium.
What is the number of neutrons uranium?
The number of neutrons in the nucleus of an atom varies. Let's look at the issues. First, hydrogen is an "odd bird" in the periodic table. It is far and away the most common element in the universe, but most of it (over 99.98% !) has on a lone proton for a nucleus. A tiny bit has one neutron, and an even smaller bit has two neutrons. That said, let's look at the "general population" of the periodic table. Lighter elements have about a one-to-one ratio of neutrons to protons. This ratio creeps up as we move up the periodic table, and it is over two to one (neutrons to protons) at the upper end of the table. Each element has a number of different isotopes, and each isotope has a different number of neutrons in its nucleus. The bottom line is that each isotope of each element will have to be considered individually to determine the number of neutrons in its nucleus.
What does Ai mean on periodic table?
"Ai" is not a standard element symbol on the periodic table. It may be a typo or error. The periodic table typically uses two-letter symbols to represent elements, such as "Al" for aluminum or "Ag" for silver.
What are two substances on the periodic table that are not an element compound or mixture?
Two substances on the periodic table that are not elements, compounds, or mixtures are isotopes and allotropes. Isotopes are atoms of the same element with different numbers of neutrons, while allotropes are different forms of the same element in the same physical state.
What is the symbol for He in the periodic table?
The name of the element with symbol 'He' is Helium. It has got 2 Protons and two neutrons in the nucleus and 2 electrons moving around it. It is first in the series of 'Nobel' gases. Others being Neon, Argon, Krypton,Xenon and Radon.
What does the letter i stand for on the periodic table?
The letter "i" does not represent any specific element on the periodic table. The elements on the periodic table are typically represented by one or two letter abbreviations.
What 2 numbers are shown in tye periodic table for each element?
The number above the symbol is the atomic number, or the number of protons in the nucleus of one atom of the element. It is this number by which they organized the periodic table. If this number changes so does the identity of the element. In a balanced atom this number will also be the number of electrons in the electron cloud. The number below is the atomic mass number, or the average number of particles (protons plus neutrons) in the nucleus. Since the number of neutrons can change this number must be given as an average so it may contain a decimal.
