Molecular size a bit tricky. As a quick comparison, we can use the covalent radius defined as 1/2 the distance between to identical covalently bonding nuclei. This is measured in picometers (1 pm= 1x 10-12 m). Nitrogen's covalent radius is 75pm so the length of a nitrogen (N2) molecule ought to be 4 X 75pm or 300 pm. A molecule of oxygen (O2) ought to be just a shade smaller 4 X 73pm or 292pm. So an oxygen molecule is a little less than 3% smaller than a nitrogen molecule.
Nitrogen is a non meta element. Atomic number of it is 7.
Nitrogen's atomic number is 7. This is because nitrogen has 7 protons in its nucleus, which determines its atomic number. The atomic number defines the identity of an element and its position on the periodic table.
The atomic size of oxygen is approximately 60 picometers (pm). The atomic size refers to the distance from the nucleus to the outermost electron shell in an atom.
Potassium has a bigger atomic size than copper. This is because as you move down a group in the periodic table, the atomic size generally increases due to the addition of more electron shells. Potassium, being below copper in the periodic table, has a larger atomic size.
Could you please re-ask your question in a better manner, because that question does not make sense. Are you trying to ask the atomic mass of the element with the atomic number of 7? or are you just stating that there is an element with the atomic number of 7? because that is not a very good question.
Nitrogens Atomic # is 7
Nitrogen is a non meta element. Atomic number of it is 7.
Nitrogens' atomic weight is 14.00647. It comprises %79 of the Earths air.
Nitrogen's atomic number is 7. This is because nitrogen has 7 protons in its nucleus, which determines its atomic number. The atomic number defines the identity of an element and its position on the periodic table.
nonmetal
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
atomic mass - 14 atomic number - 7 It has that because it has 7 protons (and electrons) = the atomic number. And it also has about 7 neutrons and roughly, the mass number = the number of neutrons+ the number of protons.
Azote
The atomic size of oxygen is approximately 60 picometers (pm). The atomic size refers to the distance from the nucleus to the outermost electron shell in an atom.
atomic size decreases across a period
No. It is a liquid.
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
