How many atomic number in hydrogen?
Hydrogen is a non meta element. Atomic number of it is 1.
What are the atomic number for the hydrogen isotope with 1 neutron?
Atomic number of hydrogen is (always) 1. The mass number is 2, sum of number of protons (1 in H) and neutrons (1 in H in this case). This isotope of hydrogen is called deuterium.By the way: neurons (without t) is a very different thing!
If the atomic number of iodine is 53 how many bond will it make with hydrogen?
One covalent bond is between iodine and hydrogen.
Why is hydrogen located in Group1a of the period table?
because of its atomic number / how many electrons are in it
How many electrons are there in hydrogen deuterium?
Hydrogen has 1 electron while deuterium, which is an isotope of hydrogen, also has 1 electron. The number of electrons in an atom is determined by the atomic number of the element, which is 1 for hydrogen.
How many electrons does this element have O?
The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8. For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
How many protons does a standard hydrogen have?
A standard hydrogen atom has 1 proton. The Atomic Number of any element is the number of protons that element has.
What is the atomic number determined by?
The number of protons the specific element has. Example, Hydrogen has 1, Helium has 2, Lithium has 3...etc etc etc Not to be confused with atomic mass.
What are the atomic numbers and atomic mass?
Atomic Number :- atomic number of an element is the number of protons present in the nucleus of the atom. (since atoms are electrically neutral the number of protons in an atom is equal to the number of electrons in an atom) Atomic Mass :- atomic mass of an element is the number which tells us how many times an atom of that element is heavier than an atom of hydrogen (whose atomic weight is taken as unity [1])
Why can't the mass number be smaller than the atomic number?
The mass number has to be greater then the atomic number because the mass number is the protons plus the neutrons. If you were to take 10-12 you would get a negative number of 2 and there can't be a negative number of neutrons!
Whats the number of protons for all the periodic elements?
The atomic number of an element tells you how many protons it has. For example: Hydrogen is number one on the table, atomic number 1, therefore it has just 1 proton. Carbon is number 6 on the periodic table, atomic number 6, number of protons = 6
How many hydrogen atoms are necessary to join with oxygen to make it a stable compound when oxygen has an atomic number of 8?
Oxygen always has atomic number 8, but that has nothing directly to do with the rest of the question. The number of hydrogen atoms needed is 2, because that is what must be shared to fill the "outer shell" of both the oxygen atom and each hydrogen atom.
