This artificial element exist - ununseptium (temporary named) with the symbol Uus.
It is in "Group 17".
Protons and neutrons because they are in the nucleus, electrons are around the nucleus.
Lithium The element number represents the number of protons in its nucleus. That means the smaller number a element has, the lighter it will be. Lithium is the third element.
The number of the protons in the nucleus of a chemical element is equivalent to the atomic number; the atomic number define the position of this element in the periodic table (group, period). And from these we can suppose the chemical properties of this element.
It should belongs to group 17.
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.
Protons and neutrons because they are in the nucleus, electrons are around the nucleus.
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.
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.
Atoms are determined to belong to a specific element based on the number of protons in their nucleus. The atomic number of an element corresponds to the number of protons in the nucleus of its atoms. This number is unique to each element and is used to identify and categorize atoms into their respective elements.
Lithium The element number represents the number of protons in its nucleus. That means the smaller number a element has, the lighter it will be. Lithium is the third element.
The number of the protons in the nucleus of a chemical element is equivalent to the atomic number; the atomic number define the position of this element in the periodic table (group, period). And from these we can suppose the chemical properties of this element.
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.
The atomic number defines an atom's identity, i.e. element. A group of atoms contatining the same number of protons in their nuclei belong to the same element even if they can have different numbers of neutrons or electrons associated with them. If two atoms have the same number of protons but different number of neutrons, they are called isotopes. If an atom has less or more electrons than its number of protons, it is known as an ion. In certain instances during radioactive decay, the number of protons in an atom's nucleus can actually change. This results in a transmutation (change of one element to another).
It should belongs to group 17.
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 sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
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.
