Cl is above and to the right of Se so Cl is smaller
O is above and to the right of P so O is smaller
Save
P is above but to the left of SE- cannot compare using periodic table only
ANSWER
P AND O
The atomic number of the Periodic Table element Period is 92.
The atomic number of the element lanthanum on the periodic table is 57.
NO!!! Hydrogen (H) is the first element on the Periodic Table. Reason Atomic No. = 1 Atomic mass( of protium) = 1 Carbon lies 6th position. Atomic No. = 6 Atomic mass = 12
The atomic number of the element with the symbol "Pt" on the periodic table is 78.
The atomic number of the element that belongs to the s-block in the periodic table is 2.
The atomic number of the Periodic Table element Period is 92.
The atomic number of the element lanthanum on the periodic table is 57.
The element with the largest atomic number on the periodic table is Oganesson, with the atomic number 118.
Atomic mass, also known as atomic weight, is the average mass of an atom of an element based on the relative abundance of its isotopes. It is listed in the periodic table below the element's symbol. Atomic mass is measured in atomic mass units (amu) and provides information about the element's mass compared to a standard carbon-12 atom.
The atomic number on the periodic table is the number of protons for the element.
NO!!! Hydrogen (H) is the first element on the Periodic Table. Reason Atomic No. = 1 Atomic mass( of protium) = 1 Carbon lies 6th position. Atomic No. = 6 Atomic mass = 12
The atomic number of the element with the symbol "Pt" on the periodic table is 78.
Atomic number of an element can be found on the periodic table. It is located at the upper left-hand corner of the table.
The atomic umber of an element listed in the periodic table refers to number of protons in the element. Atomic number is equal to number of protons.
No element has an atomic weight of 19.32 on the periodic table.
YES!!! The atomic No. is the postition of the element in the periodic table. It also indicates the number of protons in the element and electrons in the neutral element. The Atomic Mass is also included in the periodic table. The Atomic Mass is the sum of all the protons and neutrons of an element in the periodic table. Here are some examples. Hydrogen ; [1/1]H The first element in the table Carbon ; [12/6]C The sixth element in the periodic table Oxygen ; [16/8]O The eighth element in the periodic table et.seq., The first number given is the Atomic Mass and the second number is the Atomic Number.
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
