Why is magnesium located to the right of sodium in the periodic table?
In amy line accrues the periodic table each step to the right indicates that the element contains one more proton than the element to its left. Nickel has one more proton (28) than cobalt (27) and occupies its proper position.
How do the number of protons identify an atom?
The elements are defined by their number of protons.There are about 118 known elements (see the Periodic Table of the Elements) and all have a different number of protons.The number of protons is indicated on the Periodic Table by the proton number or atomic number. Hydrogen is proton number 1 and all hydrogen atoms have one proton per nucleus.Helium is proton number 2 and all helium atoms have two protons per nucleus. Lithium is proton number 3 and all lithium atoms have three protons per nucleus. And so it goes on. Calcium has the proton number 20 and thus there are 20 protons in the nucleus of each calcium atom.If you find a calcium atom with more or less than 20 protons in the nucleus, then you are wrong and what you have before you is not calcium.Elements are defined and distinguished by the number of protons. Find out the number of protons for each element by looking at the proton number of each element on the Periodic Table. There is a continuous sequence of elements on the Periodic Table from proton number 1 to proton number 118!
This element has one less proton then sodium?
Neon, Ne
What predicts an element's properties?
The answer you are probably looking for is the periodic table, which arranges the elements. The periodic table can help predict properties of an element based on the element's location. All the elements in a veritcle collum (also known as family or group) will have the same number of valence electrons and thus behave in a similar manner. Elements can also be compared to one another on the horizontal axis(the period). i.e. moving from left to right elements become less metalic and do not exibit metallic properties as stongly. General location on the table can tell you what type of element it is; metal, nonmetal, metalloid/semimetal. or the # of protons and electrons in the element, the atomic mass.
Why are the two bottom rows of the periodic table not attached to the rest of the table?
because they are less important metals
Why is magnesium located to the right of sodium in the periodic table?
In amy line accrues the periodic table each step to the right indicates that the element contains one more proton than the element to its left. Nickel has one more proton (28) than cobalt (27) and occupies its proper position.
Why is the atomic number included in the periodic table?
Presumably because atomic number is the fundamental characteristic for organizing the periodic table itself. Every element in the interior of a period of the periodic table has an atomic number greater by 1 than its neighbor to the left and less by 1 than its neighbor to the right; every element (except hydrogen) at the left end of a periodic table period has an atomic number greater by one than the rightmost member of the preceding period; and every element at the right end of a periodic table periodic has an atomic number less by 1 than the leftmost element in the succeeding period, if such a succeeding period exists.
What makes each element different from the previous one?
The previous element in the periodic system (by ordered atom number) has ONE proton and one electron LESS per atom

What element has one less proton than aluminum?
maybe proton
Why isnt the mass of the electron included in the mass of an atom on the periodic table?
the mass of electron is very less compared to that of a proton or a neutron it is 1/1800 the mass of 1 proton and therefore it is negligible and not included.
What is cation and where can you find it on periodic table?
a cation is not an element, it is a positively charged ion, which means that it has less electrons than protons
What is the name for the 117th element on the periodic table?
Ununseptium is the name for the 11th element. It symbol is Uus. It's half-life is less than one second.
What is the lowest atomic number in the periodic table?
Atomic number: The number of protons in an atomic nucleus. (http://www.answers.com/topic/atomic-number) So the lowest atomic number is 1, which is hydrogen, as you cannot have an element with less than one proton.
Are there millions of element?
As far as we know, there are much less than a million. All of the known elements in the world are listed on the Periodic Table of Elements.
How do you use the periodic table to find what forms when neptunium disintegrates?
After an alpha decay the atomic number of the new element formed is less with 4.
Is There are about 100 metals in a periodic table?
a little less. but the periodic table is made up of mostly metals
