What is the smallest atom in the second row of periodic table?
The smallest element known to man is Hydrogen (H).
What is the smallest atom in group 6A and gains 2 electrons to become chemically stable?
The smallest atom in group 6A is oxygen. Oxygen gains 2 electrons to achieve a stable electron configuration by forming an oxide ion with a 2- charge.
What is the smallest number of atoms in one molecule?
the smallest atom is hydrogen, the smallest molecule would be the naturally occurring diatomic hydrogen.
What is the smallest atom in water?
A single drop of water contains about 2 sextillion (2×1021) atoms of oxygen.
A helium atom has?
an atomic number of 2 and an atomic weight of about 4. So it has 2 protons, 2 neutrons, and 2 electrons. It has a complete valence shell (the smallest atom with this attribute) which makes it the smallest noble gas. It has a cas# of 7440-59-7... I'm not sure what you're asking. I can go on but it would be better if you'd ask a more specific question. You can email me too.
Is neon the smallest radius in period 2?
yes! It is because Neon has the largest atomic mass so the force of attraction between electrons and protons in the positively charged nucleus is the highest compared to all the other electrons in period 2.
What can you tell about an atom that comes from a period 2?
It has two electronic shell and its highest quantum no is 2
Which has the smallest volume 1 the nucleus of an oxygen atom 2 a water molecule 3 a proton 4 an ice crystal 5 or an electron cloud of an oxygen atom?
Proton
Is the smallest unit of a chemical compound that retains the properties of the compound?
Molecule
What element is found on period 4 and has 7 valence electrons?
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
What is the smallest class of the periodic table?
The smallest class of the periodic table would be the semi-metals, or metalloids. The second biggest group would be the nonmetals. The largest group would be the metals.
A covalent compound formed between an element in period 2 and a halogen?
An example of a covalent compound formed between an element in period 2 and a halogen is hydrogen fluoride (HF). This compound is formed by the sharing of electrons between the hydrogen atom (period 1) and the fluorine atom (halogen).
