What general trend in electronegativity do you note going down a group across a period?
going down a group, electronegativity decreases going across a period, electronegativity increases
Rank these elements in terms of increasing atomic radius?
In terms of atomic radius, the sequence would be oxygen, carbon (both period 2), magnesium (period 3), rubidium (period 4), and cesium (period 5). Note that order by periods is not absolute: in each period, the elements toward the far left side have the largest radii. For example, the radius for lithium in period 2 is larger than almost all of the elements in periods 3 and 4. *Numerically, the elements O, C, Mg, Rb, and Cs have respective radii of about 60, 70, 150, 235, and 260 picometers.
How many radi in a circle?
There are an infinite number of radii in a circle.
What is the periodic trend for atomic size from top to bottom in a group?
Atomic size generally increases from top to bottom within a group on the periodic table. This is because each successive element has an additional energy level of electrons, leading to increased electron-electron repulsion and an overall increase in atomic size.
What is the atomic number of thulim?
The atomic number of thulium [note correct spelling] is 69.
What is the atomic number of chronium?
The atomic number of chromium [note correct spelling!] is 24.
What is the atomic number of sodiumhydroxide?
Sodium hydroxide {note presence of a space between words} is a compound and does not have any atomic number; atomic numbers are characteristics of atoms only.
Who was the elizabethen period named after?
The Elizabethan (note spelling) period was named for Queen Elizabeth I
What is the atomic number of MN?
Manganese is a metal element. Atomic number of it is 25.
How does a dotted half note look?
a half note with a small dot to the right of it (like a period)
What is the atom weight of hydrogen?
The atomic weight of hydrogen is 1,007 94 ± 0,000 07 atomic units of mass.
How do you determine the number of neutron?
Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number *A note on Atomic Mass* Atomic Mass is the sum of the number of protons and neutrons in an atom. Every time you remove or add a Proton/Electron or a Neutron, you change the mass by one. *A note on Protons and Electrons* The number of Protons and Electrons in an atom is always the same. Whenever you talk about adding/removing a proton or an electron, you are by default adding/removing one of the other as well.
