How can you use the periodic table to find the number of protons in one atom of an element?
valence electrons is the same as the number as the last digit in the group :)
The alkaline earth element having the largest atomic radius is found in period?
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
What group does oxygen belong?
Oxygen is the first element in group 16 of the periodic table
What element is an example of an alkaline earth metal?
None. The alkaline earth metal isotope with the fewest neutrons would be beryllium-7 with three neutrons and a half-life of 53 days.
How many protons neutrons and electrons are in element beryllium?
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.
What is the element that has the most protons of any element in group 18?
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.
What element had the fewest valence electrons?
hydrogenhydrogen------------------------------------------------------Put the following elements in order, with the element having the most valence electrons at the top of your list and the element with the fewest valence electrons at the bottom.NEONCHLORINESULFURNITROGENSILICONBORONCALCIUMSODIUM
What element is a metal of group 4 with 28 protons?
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.
What group would a element synthesized with 115 protons group?
The element with 115 protons is arbitrarily named as Ununpentium and it belongs to group 15, nitrogen family.
Why does the mass of the elements increase when you go down the periodic table?
The number of protons, neutrons and electrons for each atom increases as you go down a group. Hydrogen is the lightest element as it has the fewest sub-atomic particles.
Which element has the fewest valence electrons?
These are the alkali metals (group 1 of the periodic table).
Where on the periodic table would you find the element with seven protons?
Nitrogen is the element with 7 protons. It is place din period -2 and group-15.
What element in the Periodic Table has 85 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.
Which element has the most protons of any 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.
What element has the most protons of any element than any element in group 15?
Uup, or ununpentium with 115 electrons
What element is in group 1 with 37 protons?
If you look at a periodic table and go to group one, and than the element with an atomic number of 37 it is Rb. The atomic number is the number of protons and electrons. Rb is Rubidium.
Which group 2 element has fewer protons than bromine but more protons than sulfur?
calciumThe element sulfur's atomic number is 16, so there are 16 protons in its nucleus. The element bromine's atomic number is 35, and there are 35 protons it its nucleus. This means the element will have an atomic number between 16 and 35. Since the question asked which Group 2 element fits in that window, we can go to the periodic table and look down the column of Group 2 elements and find that calcium is the element so described. It has the atomic number 20, and that means 20 protons in its nucleus.Remember that the Groups on the periodic table of elements are the vertical columns, and they range from Group 1 to Group 18. Group 2 elements are the so-called Alkaine Earth metals. A link is provided to the Wikipedia post on the periodic table. Bookmark this one, kids! Each element on the table is a hyperlink to the Wikipedia post on that element. Even the Group numbers are hyperlinks to the post on that Group! It just doesn't get any better that that.
