For Groups 1 and 2 the valence number is the group number, for groups 13-18 it is the last digit of the group number so oxygen (group 16) would have 6 valence electrons. For all the other groups ( group 3-12, the transition metals ) they are variable.
The element with atomic number 118 and 8 valence electrons is oganesson (Og). Oganesson belongs to the noble gas group and has a complete outer shell of valence electrons, making it stable and unreactive.
Ununoctium has 118 protons, 118 electrons and 176 neutrons.
118 protons and 118 electrons, as its atomic number is 118.
Ununoctium has an atomic number of 118, in the neutral atom it will therefore have 118 electrons.
116 protons and electrons Number of neutrons = Atomic mass of an isotope - Atomic number of the element; Uuq has many isotopes, each with a different number of neutrons.
Who told you that chromium had 118 electrons - there are only 24. Check it out with Wikipedia. There you find the element that really has 118 electrons. Happy hunting. (PS - Hint - there is a very close correlation between the number of electrons and the atomic number of the element.)
Ununoctium has 118 protons, 118 electrons and 176 neutrons.
Hg2+ has 118 electrons. Each mercury (Hg) atom contributes 80 electrons, so two atoms in Hg2+ contribute a total of 160 electrons. Since it is a +2 cation, it has lost 2 electrons, resulting in a total of 118 electrons.
Every type of atom currently know to man. It consists of 118 elements, though the number is always changing.
all atoms have different numbers of electrons hydrogen=1 Ununoctium=118
79 protons, 79 electrons and 118 neutrons. a neutral gold atom has 79 protons about 121 neutrons and 79 electrons
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
