Electron
It will bond with sodium to create NaCl, salt. This is because it has more attractive force. Take a look at an activity series that will tell you which elements will form a compound over another element in a chemical reaction. See the link below.
If it is a non-metal to non-metal bond than it is covalent. For example, CO2 is a covalent bond.
Tell the Bond Girl to GET OUT
The name helium tells that its atomic number is 2, containing 2 protons in each atom. The numerical part of the name shows that each atom also has one neutron.
The francium atom is larger.
It would tell you how many neutrons make up the Nucleus of the atom.
The atom also has 15 electrons.
you can tell an atom has a negative charge if its outer shell is not stable(happy)/full
If the number of protons and neutrons are the same, its an atom, if not its an ion
An Ionic bond is one where an element gives away electrons to another, forming Ions. It usually occurs between metals and nonmetals. Another way to tell is if the electronegativity difference between the elements is greater than 2.0 then it is an ionic bond. A covalent bond is one where the elements share electrons with one another. It usually occurs between nonmetals. If the electronegativity difference between the elements is 2.0 or less it is a covalent bond.
The electrons on the outermost shell of an atom tell you how many valence electrons an atom on the periodic table has , and this number can be used to apply to the octect rule .
you need to tell me which part of the temple your in submit another question and tell me.
