Answer:
18
Explanation:
6 (weights) x 3 (distance) = moment
Electronegativity means how strongly an atom can attract electrons. The more positive charge an atom has, the better it attracts the negatively charged electrons. However, distance is a factor too, so if the nucleus (where the protons are) starts becoming too large, the strength of the positive charge isn't as large as it would otherwise be.
Basically this means that fluorine is the most electronegative element since it has the most positive charge for its relative size. Elements closer to fluorine have higher electronegativities than elements further from it on the periodic table.
so in other words F is most electro, bc it attracts more electrons to its atom making other atoms Positive
The atom that is made up of two protons is He. The number of neutrons is also two. The number of electrons matters in the charge. So to make 10 electrons, we add 8 more. hence, 4/2 He 8-.
Answer:
1 dm
Explanation:
Centimeter and decimeter both are units of length.
Centimeter is represented as "cm" while decimeter is represented as "dm"
centimeter is larger than decimeter. One centimeter have 10 decimeter.
1 cm = 10 dm
So in order to convert cm to dm we will divide the given value by 10.
10 dm × 1 cm/10 cm
1 dm
Answer:
Atoms of elements at the top of a group on the periodic table are smaller than the atoms of elements at the bottom of the group. ... The valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the bottom are more reactive than those at the top.
