What is the first metal in the periodic table?
Going by atomic number, Lithium (Li) is the first metal present with the atomic number of 3.
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What is the atomic number of NaCI?
Atomic numbers are only given to individual elements. I'm not sure what you were going for here, but only individual atoms (Na or Cl) have atomic numbers. See the periodic table.
Is there an easy way to remember that on the periodic table the atomic number goes on top of a square and the atomic mass is the one the bottom?
To be honest, as far as I know, no.However, I don't think it's a horrible lot you have to remember... and I'd be surprised if you don't get a periodic table when going to an exam.Well if you can remember the atomic number the atomic mass is a little more or less than the doubled atomic number.Atomic numbers are pretty simple to memorize. If your test is multiple choice even easier. Ask your teacher if you can use a blank periodic table unless that's the test
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
What explains the observed trend in the atomic radii going down the periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
What best explains the observed trend in atomic radii going down periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
What is an atomic group?
Each column going down the periodic table is an atomic group.
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
Why do atomic radii generally get larger going down the periodic table?
As more energy levels are occupied by electrons, the atomic radius gets larger.
What is the first metal in the periodic table?
Going by atomic number, Lithium (Li) is the first metal present with the atomic number of 3.
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What is the atomic number of NaCI?
Atomic numbers are only given to individual elements. I'm not sure what you were going for here, but only individual atoms (Na or Cl) have atomic numbers. See the periodic table.
What is periodic table or periodic chart?
The periodic table or chart is a display of all chemical elements which are ordered by atomic number.the atomic number simply tells you how many electrons there are in the atom. It was created by Dmitri Mendeleev then helped change by Henry Moseley because Dmitri Mendeleev had ordered it in atomic mass. It is used to predict where chemical elements are going to be found and where.
What happens to the atomic numbers on the periodic table looking from left to right?
it grows one more with each element going right
What trend is generally observed in electronegativity going across the periodic table from left to right?
From left to right and into the upper corner of the periodic table electronegativity increases. Fluorine is the most electronegative element, but the elements in group 18 generally have no electronegativity at all.
What property increases going down the periodic table?
Your question is incorrect. It should be increases rather than decreases. Well it is the proton number (Z) that increases.
