Q. Which of these elements in period 3 has the least tendency to attract electrons?
Which element in Period 3 has the least tendency to lose an electron? Argon is a noble gas. It does not gain nor lose an electron.
Q. Do Group 3 elements gain or lose electrons?
Most elements in Group 3 lose three electrons to form 3+ ions. Boron, however, shows little tendency to form ions. It obtains a noble gas structure by sharing electrons with other atoms. This is called covalent bonding.
Q. Why do group 5 elements gain 3 electrons?
The Group 5A elements have five valence electrons in their highest-energy orbitals (ns2np3). Nitrogen, phosphorus, and arsenic can form ionic compounds by gaining three electrons, forming the nitride (N3-), phosphide (P3-) and arsenide (As3-) anions, but they more frequently form compounds through covalent bonding.
Q. What happens if an atom loses or gains an electron?
An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).
Q. How do you know how many electrons an atom will gain or lose?
Hint: The “Group Number” on the periodic chart tells you the number of electrons in the outermost shell. From that you can tell how many electrons the atom needs to lose or gain to equal 8.
Q. What happens to electrons when they gain energy?
When electrons gain or lose energy, they jump between shells as they are rotating around the nucleus. Then, as they lose energy by emitting photons, they might move back to the second energy level shell or even to the first energy level shell.
Q. What is the role of high energy electrons?
High-energy electrons are released from NADH and FADH2, and they move along electron transport chains, like those used in photosynthesis. This energy is used to pump hydrogen ions (from NADH and FADH2) across the inner membrane, from the matrix into the intermembrane space.
Q. What is the energy of infinite shell?
The H atom has an infinite number of energy levels spanning a finite energy range. This range is 13.6 eV, the ionisation energy, and is equal to the Rydberg R in energy. In the simplest (basic) theory the energy is En=−R/n2, where n is the principal quantum number, n=1..
Q. Does an atom have infinite energy?
Explanation: Every atom has an infinite number of energy levels available, depending on how much energy has been absorbed. In the ground state, there are seven (known/most-often-seen) energy levels which may contain electrons.
Q. What does infinite energy level mean?
As for infinite energy levels, give the hydrogen atom’s electron enough energy and it will escape the hydrogen nucleus and therefore produce no emission spectra. So the hydrogen emission spectra are limited to those energy levels where the election is still held by the nucleus.
