Which is the least reactive Mg Li or Be?
Be is least reactive its outermost orbital 2s is completely filled so its electron affinity is almost zero.
Why electron affinity of beryllium is zero?
Electronic configuration of beryllium: 1s2.2s2.
What name is given to a region of an electron probability density graph where the probability of finding the electron is zero?
The region of zero electron density is called a "node."
Why the first electron affinity is negative?
The electron affinity, or EA, of nitrogen is less than zero (EA = -7) because of is electron configuration, which is [He] 2s2 2p3. Nitrogen, as a neutral atom has a half-filled p-orbital, and by Hund's Rule, that means that each p-orbital has 1 unpaired electron. In the same way that a completely filled orbital is especially stable (like the noble gases), a half-filled orbital IN A NITROGEN ATOM IS HIGHLY UNSTABLE ([He] 2s2 2p4).In contrast, carbon, C, has a much larger electron affinity (EA = -123.4 kJ/mol) because it has electron configuration [He] 2s2 2p2, which means that the addition of one more electron will bring it to an extra stable half-filled shell. Fluorine of course has an extremely high electron affinity (EA = -331.4 kJ/mol) because of it's electron configuration, [He] 2s2 2p5, where the addition of one more electron gives it a completely filled valence shell or noble gas configuration, [He] 2s2 sp6.
What is the angular momentum of an electron in 2s-orbital?
Zero.
Which is the least reactive Mg Li or Be?
Be is least reactive its outermost orbital 2s is completely filled so its electron affinity is almost zero.
Define sparse matrix?
A matrix that have one or more elements with value zero.
Why zero group elements are mono atomic?
Atoms of these elements do not combine with other atoms, even atoms of the same element, because their valence electron shells are full.
When is the mass of an electron regarded as zero?
The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.
Why electron affinity of beryllium is zero?
Electronic configuration of beryllium: 1s2.2s2.
What is the value of zero?
The value of zero is zero. Zero is always going to have a value of zero.
What name is given to a region of an electron probability density graph where the probability of finding the electron is zero?
The region of zero electron density is called a "node."
Does zero have any value?
of course it has - a value of zero - so if something times zero is zero - it must have a value

In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
What is the angular momentum of an electron in 2s-orbital?
Zero.
How many lone pairs electron in CCl4?
