As you go down the periodic table, electronegativity decreases. As you go across the pt, it increases. It is the same trend as ionization energy.

Answer from: joc223

The tendency of an atom in a molecule to attract the shared pair of electron towards itself is called its electronegativity. Highest value of electronegativity. [for fluorine] is taken as 4.0 and the lowest one[for caesium] as 0.7 Electronegativity. depends on Atomic SizeGreater the size of the atom,the lesser the electronegativity,since the electrons being further away from the nucleus experience a lesser force of attraction. Nuclear Charge---The greater the nuclear charge,the greater the electronegativity,because increase in nuclear charge causes electrons to be attracted by a greater force, Trends in Electronegativity Across a period Since the nuclear charge increases due to an increase in atomic number,electronegativity increases from left to right in a period, For example,in the second period,electronegativity increases from lithium to fluorine, Down a group There is an increase in atomic number down a group, i.e. nuclear charge increases,but due to the addition of extra shells,the atomic size increases.The effect of an increase in the atomic size overcomes the effect of an increase in the nuclear charge,hence electronegativity decreases down a group. For example,in the first group it progressively decreases from lithium downwards to francium.

Electronegativity increases as you move across and up the Periodic Table to Group 17, making fluorine (F) the most electronegative elemen

Answer from: Quest

If a hydrogen atom is neutral, it must also have one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
