Which alkaline earth metal has the lowest atomic number?
Beryllium has the lowest atomic number among the alkaline earth metals.
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.
Which element has the lowest atomic number transuranium?
The element with the lowest atomic number among the transuranium elements is neptunium, with an atomic number of 93. It is the first transuranium element produced synthetically in a laboratory setting.
Which is the lightest substance among these four 1oxygen 2nitrogen 3hydrogen 3carbon?
Hydrogen is the lightest substance among these four elements. It has the lowest atomic number and atomic weight, making it the lightest element on the periodic table.
What family of elements has the lowest atomic radius?
The noble gases have the lowest atomic radius among all the elements. This is because they have a full outer electron shell, leading to minimal atomic size.
What alkaline earth element formed the smallest number of precipitates?
Beryllium forms the smallest number of precipitates among the alkaline earth elements.
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.
What come first cotton ball iron helium rubber?
Helium comes first because elements are arranged by atomic number on the periodic table. Helium has an atomic number of 2, which is the lowest among the listed materials. Then comes cotton ball, rubber, and iron in that order.
Which of these elements has a smaller atomic number Nitrogen Aluminum Potassium?
Nitrogen has the smallest atomic number among the elements listed. Aluminum has an atomic number of 13, Potassium has an atomic number of 19, and Nitrogen has an atomic number of 7.
What element is the smallest Li C F?
The smallest element among lithium (Li), carbon (C), and fluorine (F) is lithium. It has the lowest atomic number of the three, which is 3, while carbon has an atomic number of 6 and fluorine has an atomic number of 9. Consequently, lithium has fewer protons and electrons compared to carbon and fluorine, making it the smallest element in this group.
Which noble gas has the greatest atomic number?
That would be Astatine with the atomic number 85.
Why does francium have the biggest atomic size?
Francium is located on the bottom left side of the periodic table of elements. Meaning it has the largest number of electron shells and lowest electron negativity. Thus having the biggest atomic size.
