calcium
The 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.
Calcium (Ca) is a group 2 element having fewer protons than bromine but more protons than sulfur.
Calcium. Calcium has 20 protons, sulfur has 16, and bromine has 35.
calcium
Radium
Carbon is the element in the same family as lead with atomic number less than sodium.
Sulfur: The periodic column containing elements with two fewer electrons than the noble gases is column 16, in which oxygen, the lightest element, has a mass number of 16. Sulfur, the next element in this column, has a mass number of 32.
Argon, atomic number 18, since it is between chlorine and potassium on the Periodic Table of Elements.
The periodic table is a good reference - check out the atomic number ! Helium - 2 protons, Nitrogen - 7 protons
They have the same number of protons in the nucleus and same number of electrons surrounding the nucleus.
Calcium. Calcium has 20 protons, sulfur has 16, and bromine has 35.
potassium
Sulfur. definitely Sulfur
Sulfur (S)
This would be Sb - Antimony.
