The element with the fewest protons found in group 2 of the Periodic Table is beryllium (Be). It has 4 protons in its nucleus. Beryllium is an alkaline earth metal and is located in the second column of the periodic table.
valence electrons is the same as the number as the last digit in the group :)
7th period because atomic size down the group increases. And Alkali Earth metals are found only in Group 1. The element is in Group 1 and period 7
Oxygen is the first element in group 16 of the periodic table
None. The alkaline earth metal isotope with the fewest neutrons would be beryllium-7 with three neutrons and a half-life of 53 days.
Beryllium should be expected to have a charge of 2+ as is expected of all the elements in Group 2 of the periodic table. But its behavior is somewhat different than other Group 2 elements because it has so few electrons. This element tends to form covalent bonds.All nuclei have a positive charge.So beryllium-9 has a positive charge.
The fifth period transition element with the fewest protons is zirconium (Zr), which has an atomic number of 40. It is located in group 4 of the periodic table and is known for its high resistance to corrosion and high melting point. Zirconium is commonly used in nuclear reactors and various alloys.
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.
The element in the Periodic Table that has 85 protons is Astatine. This element is in the Halogen Family (Group 17 in the Table). This group includes the elements Fluorine, Chlorine, Bromine, and Iodine.

The element in group 2 with fewer protons than potassium is beryllium. Beryllium has 4 protons in its nucleus whereas potassium has 19 protons. Both elements are found in group 2 of the periodic table.
There is no element with 28 protons in group 4. I think you are getting confused with group 4 and PERIOD 4. In period 4, the element with 28 protons is Nickel.
The element with the most protons in Group 15 of the periodic table is bismuth with 83 protons. It is in the same group as nitrogen, phosphorus, arsenic, antimony, and moscovium, but has the highest number of protons in Group 15.
The elements in group 15 are nitrogen, phosphorous, arsenic, antimony and bismuth. Bismuth has by far the most protons out of the group, with 83.
An element synthesized with 115 protons would belong to Group 15 (or Group 5A) in the periodic table. This group is known as the nitrogen group, consisting of elements such as nitrogen, phosphorus, arsenic, antimony, and bismuth.
Nitrogen is the element with 7 protons. It is place din period -2 and group-15.
Helium has the fewest valence electrons, with only 2 valence electrons.
13 protons an easy way to remember what number of protons an element has is APES. A-atomic number, P-protons, E-electrons, S-same, so the atomic number and the numbers of protons and electrons are the same number
