Nuclear charge increases across a period atoms become?
The atoms become smaller in atomic radius.
What happens between atoms during a chemical reaction?
This happens when atoms are rearanged
What subatomic particle determines atoms characteristics?
The electron.
What are some of the characteristics of solid?
tightly packed atoms
Why don't atoms simply get larger as you read across the periodic table?
because the no. of shells in the atoms across the periodic table remains the same
Nuclear charge increases across a period atoms become?
The atoms become smaller in atomic radius.
How many atoms fit across the period at the end of this sentence?
Assuming you are talking about a period made by carbon atoms (Pencil lead is almost pure carbon) and that period has a mass of 0.0001g Then the answer is 5x1018 atoms.There are 12.011g of carbon per mol, there are 6.022x1023 atoms per mol.1mol | 6.022x1023 atoms | 0.001 g |-----------|--------------------------|-------------| = 5x1018 atoms/period12.011g | 1 mol | period |
What happens to ionization energy as you move across a period?
Because energy is required to remove an electron from a neutral atom, it increases up and right. It increases up a group and to the right a period because in small atoms, electrons are closer to the nucleus were the attraction is stronger. So these are harder to remove. But in larger atoms, electrons are further from the nucleus and are easier to remove. I learned this in my Chemistry class this year. Hope this helps anyone.
What happens to size of atoms while moving across the period?
Atomic Radius Decreases from left to right. From left to right the amount of valence shell electrons increases, maxing out at 8. These valence electrons are pulled by the positively charged nucleus, thus making it smaller from left to right.
Why do the properties of elements change across the period?
They change because the atomic number and mass differ from each other element. Going across the Periodic Table to the right, the atoms get smaller because another proton is added each time so the effective nuclear charge experienced by the electrons is greater and the electrons are pulled closer to the nucleus. Electronegativity increases as you progress across a period because smaller atoms are usually more likely to gain an electron. Ionization energy increases across a period because the atoms are smaller, pulled closer to the nucleus, so it takes more energy to break an electron away.
Do oxygen atoms have different characteristics?
no
What happens between atoms during a chemical reaction?
This happens when atoms are rearanged
What are the 2 characteristics of matter?
mass and atoms
What is the characteristics of medium?
waves,atoms, and joints
What characteristics are used to describe stars?
atoms
Fr9m left to rigth in a period the size of atoms?
From left to right in a period the size of the atoms decreases.
Why don't atoms simply get larger you read across the periodic table?
because the no. of shells in the atoms across the Periodic Table remains the same
