Which has a greater attraction for electrons Ca or O?
Oxygen has a much greater attraction for electrons than calcium does.
What does elements with a higher atomic number than uranium have?
More electrons, protons, neutrons and a greater atomic weight.
How does the energy of core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
How does the energy of the core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
Compared with nonmetals the number of valence electrons in metals are generally what?
greater conductivity and higher melting points than nonmetals. Or D, because your looking at the STAR review packet. :)
Which group of elements forms bonds by using their six valance electrons?
Group 16 because on the periodic table, there are different columns that represent a greater or lesser amount of valence electrons; and group 16 has the amount of 6 valence electrons.
Why some of the periods have different numbers of elements?
The early periods have less elements because they are filling up energy levels which hold only a few electrons. The later periods contain elements with electrons in levels with a greater capacity.
What number of electrons in the outermost energy level determines how an atom will?
All the electrons in the outermost shell are relevant for chemical reactions. For many elements, the number of such electrons is between 1 and 8, but for some of the higher-numbered elements, this number can be greater than 8.
Is fluorine the most reactive nonmetal?
With greater ionization energy, nonmetals have greater reactiveness. This is because they don't want to lose electrons at all! They will instead gain electrons to complete the octet.This proves true in the element Fluorine.
Why does the second ionization energy of Group 1 Elements greater than the first ionization energy of Group 1 Elements?
It takes more energy to knock off two electrons
What element has 9 electrons?
Flourine (atomic number 9) has 9 protons and 9 electrons and 10 neutrons. Of course if it were a trick question than all elements with an atomic number of 9 or greater would hae 9 electrons :)
Which has a greater attraction for electrons Fluorine or Oxygen?
when compared to oxygen, fluorine has greater electronegativity (greater attraction for shared pair of electrons).
Which has a greater attraction for electrons Ca or O?
Oxygen has a much greater attraction for electrons than calcium does.
What determines how effective a conductor will be?
Number of electrons determine the coductivity of any conductor greater the number of electrons greater is conductivity
Which has greater mobility in intrinsic semiconductor Electrons or holes?
The mobility of electrons is always greater than holes. Only the number of electrons and holes would be same in an intrinsic semiconductor.
What has greater pull by nucleus electron in outer shell of neon or sodium?
Neon. The closer electrons are to the nucleus, the greater the pull the nucleus has on the electrons.
What does elements with a higher atomic number than uranium have?
More electrons, protons, neutrons and a greater atomic weight.
