Such an atom has a net electric charge, and is known as an ion.
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
The nucleus of an atom has both electrons and neutrons. An atom that has a positive charge means that the atom has fewer electrons than it has protons.
+3 because there are three more protrons than electrons making the charge be positive 3
An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
fewer
An atom is charged when it has more or fewer electrons than in its natural state. This is also called an Ion. Ions can be positively charged (more electrons) or negatively charged (fewer electrons).See wikipedia for a thorough dissertation
More electrons = negatively charged = anion Less electrons = positively charged = cation
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
4. two fewer electrons.
No, an atom with six electrons will try to react with another atom to gain two more electrons. Actually the fewer electrons the atom needs the more reactive it will be unless it has exactly eight valence electrons in its outer shell like a noble gas(He, Ne, Ar, etc.) Hope this helps!
Br(35) + 2p + 2e == Rb(37) The atom numbers (between parentheses) by definition are representing the number of protons in the nucleus of that element.
+3 because there are three more protrons than electrons making the charge be positive 3
The nucleus of an atom has both electrons and neutrons. An atom that has a positive charge means that the atom has fewer electrons than it has protons.
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.
an electrically neutral atom is just an atom. Atoms with more or fewer electrons (negatively charged) compared with their protons (which determines the element) are considered ions.
