Does an element that loses electrons when bonding with other atoms have a negative oxidation number?

No.
The lower (or 'more negative') the oxidation number, the more electrons the atom has.
This is because the oxidation number is a measure of the charge on that molecule and, since electrons have negative charge, more of them give a more negative oxidation number.
So if an atom loses electrons during bonding, it has lost some of its negative charge - giving it a more positive oxidation number.

Why do nonmetals have a negative oxidation number?
non metals accept electrons. Hence they show a negative oxidation number (negative denotes that the element accepts electrons)
DID OXIDATION AND REDUCTION PROCCED SIMULATANEOUSLY?
Oxidation is an element or an ion getting a positive charge by removing valence electrons and Reduction is an element or an ion getting a negative charge by gaining free electrons. In chemical reactions reduction occurs by gaining the free electrons emitted by oxidation. Therefor oxidation and reduction proceed simultaneously.Oxidation is an element or an ion getting a positive charge by removing valence electrons and Reduction is an element or an ion getting a negative charge by gaining free electrons.

What is a elements oxidation number?
A neutral atom has an oxidation number of 0. An anion has a negative oxidation number. The oxidation number of a cation is positive.
What is the most common oxidation number of nitrogen?
Nitrogen has an oxidation number of -3. Since it is in group 15, it has 5 valence electrons. It wants to have eight, so it will gain three electrons. Electrons are negative, that's why the oxidation number is negative.
What oxidation number does an atom have if it loses two electrons when bonding?
+2 for example, Be, Mg, Ca, Sr or any other group 2 element in a compound with a group 6 element

What particle of an element determines bonding?
Chemical bonding is related mainly to electrons.
What is the oxidation nu?
Oxidation number is oxidation states of an element. It can be positive or negative.
What is the meaning of the oxidation number of an element that forms an ionic bond?
The oxidation number of an element essentially tells you the charge that an element would like to achieve by bonding in order to either fill an octet of electrons or lose an outer layer of electrons exposing an octet. For example, a neutral oxygen atom will have 6 valence electrons so in order to have a full set of 8, it wants to gain 2 electrons, and since an electron has a negative charge, it has an oxidation number of -2. Sodium on the other hand has 1 valence electron, and its easier to lose this one then gain 7 more, so when it losses this electron, it will have more positive charges in the nucleus than negative charges, giving it an oxidation number of +1. Oxidation numbers are important in bonding because it determines the ratio of elements needed. In general, compounds need to be neutral, meaning the sum of the oxidation numbers of its elements must be 0. For example, Magnesium has an oxidation number of +2 and Chlorine of -1. To cancel out, you need to have 2 Chlorine per Magnesium, meaning the result will be MgCl2.
How is an element's most likely oxidation state related to its valence electrons?
It indicates how many electrons are required to complete a full valence shell.
What subatomic particle has a very small mass and a negative charge?
Electrons have a negative charge. When an element had more electrons than protons, it tends to have a negative charge.
What is oxidation number of an element?
The charge an element would have if it lost or gained electrons
Which subatomic particles are involveld in chemical bonding?
The valance electrons of an element are involved in chemical bonding.
