Chlorine.
Aluminium is a non metal element. Atomic mass of it is 26.982.
1
Indium (In) has an atomic mass of 114.818g/mol
The Atomic Mass is 17
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 atomic mass units.
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
Magnesium is a meta element. Atomic mass of it is 24.
Yes, a Group 16 VIA element can have an atomic mass larger than the element that follows it in the periodic table. An example is tellurium (Te), which has an atomic mass of about 127.6 amu, while the next element, iodine (I), has an atomic mass of about 126.9 amu. This occurs due to the varying numbers of protons and neutrons in the nuclei of these elements, leading to differences in their atomic masses.
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])
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
The element is Iodine (I). It has an atomic mass of about 126.9.
The element with the highest atomic mass is Oganesson.
