If you mean looking at the next element on the table then the mass would increase.
However, the atomic number is only the number of protons in an atom and is not a true indicator of atomic weight. Variations in Neutron count can cause differences in atomic weights.
The Atomic Mass increases as you move across the Periodic Table because the table is arranged in order of atomic number.
To elaborate, the atomic number corresponds to the number of protons in the nucleus of the atom. As the number of protons in the atom increases, so does the weight proportionally increase. Atomic weight is the average weight of all known isotopes of the element on earth. Therefore, the heavier elements will appear closer to the right and bottom of the table.
As the atomic number increases by one, the number of protons increases by one also. The weight of one more proton in addition to any added neutrons creates a heavier atomic weight.
This is a general trend, but as always, there are exceptions.
It increases based on the number of portons in the nucleus.
The number of protons and neutrons in each atom increases.
Increased central nucleus containing positively charged Protons and zero charged Neutrons.
Down a group, atomic number increases. Hence, the atomic mass also increases.
It stays the same.. :)
The atomic number and atomic masses increase as you move from left to right.
The number of energy levels increase within a group. Therefor the atomic radius increases. So the atomic volume also increases.The atomic radius also increases in a group.For metals, reactivity increases down the group. For non-metals, reactivity decreases down a group.
this elemnt has an atomic number that is double the atomic number of silicon?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
You subtract the atomic number from the mass number.
An increase in atomic number would be accompanied by a decrease in radius, and an increase in electronegativity.
The atomic number and atomic masses increase as you move from left to right.
Both the atomic number and atomic mass. among many other things. They increase the atomic number because the atomic number IS the number of protons in an atom. They increase the atomic mass because the atomic mass is the number of protons + neutrons in an atom. Basically the main two things..
Increase
The chemical reactivity of alkali metals increase when the atomic number increase.
Nothing. They are not correlated
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
decreases
They both increase
The number of electrons increases with the atomic number. So the electronegativity increases with the atomic number. Not quite. Electronegativity doesn't consistently increase with atomic number. For example, F is more electronegative than Na, even though Na has a higher atomic number.
Your question is incorrect. It should be increases rather than decreases. Well it is the proton number (Z) that increases.
To go from H to U - nevermind Be to Ba requires an increase in protons, The atomic number is defined by the number of protons
