What is the trend in the first inionzation energies as the atomic number increases across a period or row of elements?
The trend in first ionization energy across a period of elements generally increases from left to right, due to increasing effective nuclear charge (more protons) and decreasing atomic size leading to stronger attraction for the valence electrons. This makes it harder to remove the outermost electron, requiring more energy.
What else can I help you with?
How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
Does arsenic have the highest ionization energy?
No, arsenic does not have the highest ionization energy. Ionization energy generally increases as you move across a period in the periodic table from left to right. In the case of arsenic, it is found in the 3rd period, so elements to the right of it, such as bromine, have higher ionization energies.
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What type of elements tend to have low ionization energies?
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
Has largerst ionization energy in its period?
The element with the largest ionization energy in its period is typically found in the top right corner of the periodic table. This is because elements in this region have the highest effective nuclear charge, making it harder to remove an electron. In general, elements like helium, neon, and fluorine tend to have the highest ionization energies in their respective periods.
How does electronegative vary across a periodic?
The electro-negativity of elements increases as you move across a period.
How do elements changes as you across the periodic table?
the number of protons increases
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How does the number of valence electrons for elements across a period?

On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
How does the electronegativity of elements change across a period?
The electronegativity of elements generally increases across a period from left to right. This means that elements on the right side of the periodic table tend to attract electrons more strongly than elements on the left side.
What type of elements tend to have low ionization energies?
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
Has largerst ionization energy in its period?

Why does size of f block elements increase as you move across the periodic table?
because when you move it . it increases in size
Is the reactivity of the metal elements generally increases as you moves from left to right across the periodic table?
No, right to left.
