Which element has the lowest mass on the periodic table?
The atom that has the lowest mass is hydrogen. So assuming the same numbers of atoms in each element, hydrogen would be the element with the lowest mass.
Which element has lowest atomic mass in group 2 on periodic table?
Beryllium has the lowest atomic mass in group 2 of the periodic table.
Where does the metal with the lowest atomic mass go on the periodic table?
In a given period, the element with lowest atomic mass will belong to group 1. It should also be noted that lithium is the metal with the smallest atomic mass.
Where are the lowest and highest atomic masses found in the periodic table?
The element with the lowest average atomic mass is hydrogen (H) at 1.008 grams. The element with the highest is meitnerium (Mt) at 266 grams.
What is the name of the element with lowest atomic weight?
Hydrogen. It has one proton and one neutron--you can't make an atom lighter than that.
What element in the following groups has the lowest atomic mass alkali metal alkaline earth metal halogen noble gas?
Among the groups mentioned, lithium (Li) is the alkali metal with the lowest atomic mass, at approximately 6.94 u. In the alkaline earth metals, beryllium (Be) has the lowest atomic mass at about 9.01 u. For halogens, fluorine (F) is the lightest, with an atomic mass of around 19.00 u, and in the noble gases, helium (He) has the lowest atomic mass, approximately 4.00 u. Thus, helium has the lowest atomic mass overall among these groups.
What is period 4 lowest mass?
In the periodic table, period 4 elements have atomic numbers ranging from 19 (potassium) to 36 (krypton). The element with the lowest mass in period 4 is potassium (K), which has an atomic number of 19 and an atomic weight of approximately 39.1 atomic mass units.
What element in the periodic table has 4 electrons in its outer energy shell and has the lowest atomic mass in its family?
The element in the periodic table that has 4 electrons in its outer energy shell and the lowest atomic mass in its family is carbon (C). Carbon belongs to Group 14 of the periodic table, which is also known as the carbon family. With an atomic number of 6, it has the lowest atomic mass among its group, which includes elements like silicon and germanium.
Which metal has the lowest atomic number?
Hydrogen is a non metal element. Atomic number of it is 1. It is the element with lowest atomic number.
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
Which element has the lowest number of electrons?
Hydrogen, the element with the lowest atomic number.
Which element has a greater atomic mass A or B?
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.
